PREFACE.

The object of this work is to facilitate the progress of Welsh children in
the acquisition of the English language. Every one admits that it is of the
highest importance in the education of the young, that they should be well
grounded in Orthography. Thirty years' experience as a teacher having given
the author ample opportunity of noting the peculiar difficulties in the way
of Welsh children attaining a general knowledge of the English language, he
would beg leave to impress upon teachers the importance of making the
children under their care learn and spell every word in this little book,
together with the Welsh meanings. The task, though difficult at first, will
in the end reward both the teacher and the child; the former with the
pleasure of witnessing his pupil's progress, and the latter with a general
knowledge of both languages.

The book is divided into three parts: the first contains about 2013
monosyllables, arranged alphabetically, and classified according to the
number of letters. The second contains about 7497 words, arranged
alphabetically, and classified according to the number of syllables. The
third contains copious English-Welsh Dialogues.

To save the trouble of putting down twice such words as are used as nouns
and verbs, the author has placed the meaning of the noun in Welsh, and then
the verb with a colon between them. In dissyllables, the learner will
remember to place the accent on the first syllable when the word is used as
a noun, and on the latter syllable when used as a verb.

  CONVERSATIONS, &c.                    _YMDDYDDANION, &c._

  Good morning to you.                  _Boreu da i chwi._

  Good morning, sir.                    _Boreu da, syr._

  It is fine weather.                   _Mae hi yn dywydd braf._

  Delightful, after the rain we         _Hyfryd ar ol y gwlaw a gawsom._
    have had.

  Will you come for a walk to           _A ddeuwch chwi i roi tro ir_
    the country?                          _wlad?_

  I will with pleasure.                 _Deuaf gyd a phleser._

  Which way shall we go?                _Pa ffordd yr awn i?_

  Suppose we go along the road,         _Beth ped aem ar hyd y ffordd,_
    and return through the                _a dychwelyd drwy y caeau._
    fields

  Very well; let us start then.         _O'r goreu; gadewch i ni gychwyn_
                                          _ynte!_

  What o'clock is it now?               _Beth yw hi o'r gloch yn awr?_

  Half-past ten.                        _Hanner awr wedi deg._

  We must manage to be back             _Rhaid i ni ymorol bod yn ol_
    by noon.                              _erbyn hanner dydd._

  Then we had better not go             _Gwell ynte i ni beidio myned_
    far.                                  _yn mhell._

  Where does this road lead to?         _I ba le mae y ffordd hon yn_
                                          _arwain?_

  To a village about two miles          _I bentref oddeutu dwy filltir_
    off.                                  _oddi yma._

  The country air is very healthy.      _Y mae awyr y wlad yn bur_
                                          _iachus._

  It is, and does one much good.        _Ydyw, ac yn gwneud lles_
                                          _mawr i un._

  Do you know anything of this          _A wyddoch chwi rywbeth am_
    neighbourhood?                        _y gymmydogaeth hon._

  Yes, a little.                        _Gwn, ychydig._

  Who lives in that mansion?            _Pwy sydd yn byw yn y plas_
                                          _yna?_

  An independent gentleman.             _Gwr boneddig yn byw ar ei_
                                          _arian._

  He is a man of property, I            _Y mae yn wr o gyfoeth feddyliwn_
    presume.

  He is; and most of the farmers        _Ydyw; ái dyddynwyr ef ydyw_
    about here are his tenants.           _y rhan fwyaf ó'r ffermwyr_
                                          _oddeutu yma._

  Another pretty residence; who         _Dyma dŷ hardd arall; pwy_
    lives here?                           _sydd yn byw yma?_

  The clergyman of the parish;          _Offeiriad y plwyf; gwr parchus,_
    an esteemed man, and a                _a chyfaill da ir tlawd._
    good friend to the poor.

  I begin to feel the heat of the       _Yr wyf yn dechreu teimlo_
    sun.                                  _gwres yr haul._

  It does get warm: but we              _Y mae hi yn gwresogi; ond_
    shall have a fine shade presently.    _ni a gawn gysgod hyfryd yn_
                                          _fuan._

  What is it I see beyond the           _Beth wyf yn weled tu draw ír_
    bridge yonder?                        _bont acw?_

  The wind-mill.                        _Y felin wynt._

  I see the spire of a church; I        _Yr wyf yn gweled clochdy eglwys,_
    suppose this is the village.          _hwn yw y pentref debygwn._

  It is; and the building on the        _Ië; ár adeilad ár yr ochr_
    left is the school-house.             _aswy yw yr ysgoldy._

  Is the church-yard worth visiting?    _A ydyw y fynwent yn werth_
                                          _ymweled a hi?_

  Yes; but we cannot stop.              _Ydyw, ond nis gallwn aros._

  Must we go over that hill on          _A raid i ni fyned dros y bryn_
    our return?                           _yna ár ein dychweliad?_

  No; we can take the fields            _Na raid; gallwn gymmeryd y_
    along the river side.                 _caeau efo ochr yr afon._

  Is there a footpath that way?         _A oes llwybr troed y ffordd_
                                          _hono?_

  There is, and a very pleasant         _Oes, ac un hyfryd iawn hefyd._
    one too.

  Do we go over this stile?             _A ydym yn myned dros y_
                                          _gamfa yma?_

  To save that trouble the gate         _I arbed y drafferth hono, gellir_
    can be opened.                        _agor y llidiart._

  What a fine crop of hay there         _Y fath gnwd da o wair sydd_
    is in this meadow.                    _yn y weirglodd yma._

  Capital; and very soon it will        _Rhagorol; ac, yn bur fuan,_
    be ready for cutting.                 _bydd yn barod íw dorí._

  What grows in the field adjoining?    _Beth sydd yn tyfu yn y cae_
                                          _nesaf?_

  Wheat, I should think.                _Gwenith, mi feddyliwn._

  Is it not barley?                     _Ai nid haidd ydyw?_

  No; but there is a part of it         _Nage; ond y mae rhan o hono_
    oats.                                 _yn geirch._

  Is that a potatoe field beyond        _Ai cae cloron yw hwna, tu_
    it?                                   _draw iddo?_

  Yes, and a part of it set for         _Ië, a rhan o hono wedi ei osod_
    turnips.                              _i faip._

  Are much beans and peas               _A godir llawer o ffa a phys_
    raised about here?                    _oddeutu yma?_

  Yes, and cabbage too.                 _Gwneir, a bresych hefyd._

  We must walk quicker, or we           _Rhaid i ni gerdded yn gyflymach,_
    shall have a shower.                  _onide ni a gawn gawod._

  Did you hear the thunder last         _A glywsoch chwi y taranau_
    night?                                _neithiwr?_

  I did not, but fancied I saw          _Naddo; ond tybiais i mi weled_
    lightning.                            _mellt._

  It hailed about midnight.             _Yr oedd yn bwrw cenllysg tua_
                                          _hanner nos._

  A few days ago there was              _Ychydig ddyddiau yn ol yr_
    snow upon the mountains.              _oedd eira ar y mynyddoedd._

  So I have heard, and that it          _Felly y clywais, ai bod hi yn_
    was freezing hard at night.           _rhewi yn galed y nos._

  Well, we are back by the time         _Wel, dyma ni yn ol erbyn yr_
    we said.                              _amser y dywedasom._

  Yes, to the minute.                   _Ië, í'r fynud._

  When shall we go again?               _Pa bryd y cawn i fyned eto?_

  Any day next week, except             _Rhyw ddiwrnod yr wythnos_
    Tuesday.                              _nesaf oddi eithr Dydd_
                                          _Mawrth._

  Let me know on Monday                 _Gadewch i mi wybod nos Llun_
    evening, if you please.               _os gwelwch yn dda?_

  I will, if possible.                  _Os yn alluadwy, mi wnaf._

  This is my nearest way; so            _Dyma 'r ffordd agosaf i mi;_
    good bye for the present.             _felly da y bo chwi yn awr._

  Good bye, sir, and thank you          _Da y bo chwi, syr, a diolch i_
    for your company.                     _chwi am eich cwmni._

  MEAT AND DRINK, &c.                   _BWYD A DIOD, &c._

  I want my breakfast.                  _Mae arnaf eisiau fy moreufwyd._

  What would you like to have,          _Beth a ewyllysiech ei gael, syr?_
    sir?

  Make me a cup of tea.                 _Gwnewch i mi gwpaned o De._

  I am not fond of coffee.              _Nid wyf yn hoff o goffi._

  I like coffee better than tea.        _Gwell genyf i goffi, na the._

  Coffee does not agree with me.        _Nid yw coffi yn dygymmod a_
                                          _mi._

  Fetch a pound of sugar.               _Ewch i nol pwys o siwgr._

  Where from?                           _O ba le?_

  From the corner shop.                 _O siop y gongl._

  Have you any cream?                   _A oes genych hufen?_

  No; but I have some new               _Nac oes, ond mae genyf laeth_
    milk.                                 _newydd ei odro._

  Cut some bread and butter.            _Torwch fara ac ymenyn._

  Will you have some toasted            _A fynwch chwi fara wedi ei_
    bread?                                _grasu?_

  Yes, and a little cheese.             _Cymeraf, ac ychdig o gaws._

  Are there any cakes sold here?        _A oes teisenau ár werth yma?_

  Yes, but I never buy any.             _Oes, ond nid wyf byth yn prynu_
                                          _rhai._

  Are you fond of oat-meal              _A ydych yn hoff o fara ceirch?_
    cakes?

  I am.                                 _Ydwyf._

  But wheaten bread is the best.        _Ond bara gwenith ydyw 'r_
                                          _goreu._

  Some prefer rye bread.                _Mae 'n well gan rai fara rhyg._

  It does not agree with me.            _Nid ydyw yn dygymmod a mi._

  Nor with me.                          _Na chyda minnau._

  Is it dinner time?                    _A ydyw yn amser ciniaw?_

  Yes, this half hour.                  _Ydyw er's hanner awr._

  I thought so.                         _Yr oeddwn yn meddwl hyny._

  Is dinner ready?                      _A ydyw y ciniaw yn barod?_

  Yes, sir, it is.                      _Ydyw, syr, y mae._

  I feel very hungry; do you?           _Yr wyf yn teimlo yn dra newynog,_
                                          _a ydych chwi?_

  No, sir, I have no appetite.          _Nac ydwyf, nid oes arnaf_
                                          _chwant bwyd._

  What is the cause of it?              _Beth ydyw yr achos o hyny?_

  I do not know, sir.                   _Nid wyf yn gwybod, syr._

  What is for dinner to-day?            _Beth sydd i giniaw heddyw?_

  There is roasted meat.                _Mae yma gig rhost._

  Is it beef?                           _Ai cig eidion ydyw?_

  No; it is veal.                       _Nage; cig llo ydyw._

  Is it the loin?                       _Ai y lwyn ydyw?_

  No; it is the shoulder.               _Nage; yr ysbawd ydyw._

  There is also a loin of mutton.       _Mae yma hefyd lwyn o gig_
                                          _mollt._

  Is it roasted or boiled?              _Pa un ai rhostedig ai berwedig?_

  Roasted, sir.                         _Rhostedig, syr._

  I thought you had some lamb.          _Tybiais fod genych gig oen._

  No, I failed to go to market in       _Nag oes, methais a myned ir_
    time.                                 _farchnad mewn pryd._

  Have you any boiled meat?             _A oes genych gig berw?_

  There is a leg of veal.               _Mae yma goes o gig llo._

  Bring the bacon here.                 _Deuwch á'r cig moch yma._

  Who is fond of venison?               _Pwy sydd yn hoff o hydd-gig?_

  I am very fond of it.                 _Yr wyf i yn bur hoff o hono._

  May I cut some for you?               _A gaf fi dori peth i chwi?_

  A little, if you please.              _Ychydig os gwelwch yn dda._

  Have you any fowls?                   _A oes genych ddim adar?_

  Yes, I have a brace of partridges.    _Oes, mae genyf gwpl o betris._

  Is that a pigeon pie?                 _Ai pastai golomenod yw hona?_

  No; it is an eel pie.                 _Nage, pastai llyswod ydyw._

  Perhaps you would have preferred      _Feallai y buasech yn dewis yr_
    the duck.                             _hwyaden._

  I am very fond of duck and            _Yr wyf yn bur hoff o hwyaden_
    green peas.                           _a phys gleision._

  I am glad to hear; for there          _Mae yn dda genyf glywed,_
    are plenty of them to-day.            _oblegid y mae yma ddigonedd_
                                          _heddyw._

  Will you take turnips or carrots?     _A gymmerwch chwi faip neu_
                                          _foron?_

  Not any, thank you, I am satisfied.   _Dim, diolchi chwi, yr ydwyf_
                                          _wedi fy nigoni._

  Bring the cheese on the table.        _Deuwch ar caws ar y bwrdd._

  May I cut you some?                   _A gaf i dori peth i chwi?_

  A small piece, if you please.         _Ychydig os gwelwch yn dda._

  What will you drink?                  _Beth a wnewch chwi ei yfed?_

  A glass of water.                     _Gwydriad o ddwfr._

  Draw a quart of ale.                  _Gollyngwch chwart o gwrw._

  This is too sweet.                    _Mae hwn yn rhy felys._

  Draw a pint from the other            _Gollyngwch beint o'r faril_
    barrel.                               _arall._

  This is too bitter.                   _Mae hwn yn rhy chwerw._

  Mix them together.                    _Cymmysgwch hwy ynghyd._

  It is much better now.                _Y mae yn llawer gwell yn awr._

  Yes, sir, it is.                      _Ydyw, syr, y mae._

  When was this brewed?                 _Pa bryd y darllawyd hwn?_

  Last October.                         _Yn Hydref diweddaf._

  Old ale does not agree with           _Nid ydyw hen gwrw yn dygymmod_
    me.                                   _a mi._

  But fresh ale does.                   _Ond y mae cwrw newydd._

  I prefer old ale.                     _Mae yn well genyf i hen gwrw._

  Take a glass of wine with me.         _Cymmerwch wydriad o win_
                                          _gyd a mi._

  Which? port or sherry?                _Pa un? ai gwin coch, ai gwin_
                                          _gwyn?_

  Whichever you please to take.         _Yr un a weloch chwi yn dda_
                                          _iw gymmeryd._

  Allow me to give you another          _Gadewch i mi roddi i chwi_
    glass.                                _wydriad arall._

  Not any more, thank you.              _Dim yn rhagor, diolch i chwi._

  Let us now walk in the garden.        _Gadewch i ni yn awr, rodio_
                                          _yn yr ardd._

  What is the size of your garden?      _Beth ydyw maint eich gardd?_

  It is nearly two acres.               _Mae yn agos i ddwy erw._

  Is it a fruitful garden?              _A ydyw yn ardd ffrwythlawn?_

  The best in this part of the          _Yr oreu yn y rhan yma ó'r_
    country.                              _wlad._

  Have you many trees in it?            _A oes genych lawer o goed_
                                          _ynddi?_

  Yes, a great many apple trees.        _Oes, lawer o goed afalau._

  What would you like to have           _Beth a ddymunech gael i_
    for supper?                           _swper?_

  Bread and cheese.                     _Bara a chaws._

  Doctors do not recommend              _Nid ydyw meddygon yn cymmeradwyo_
    much supper.                          _llawer o swper._

  Take some cold meat.                  _Cymmerwch gig oer._

  Not any, thank you.                   _Dim diolch i chwi._

  What will you drink?                  _Pa beth a yfwch chwi?_

  A glass of small beer.                _Gwydriad o ddiod fain._

  Take a glass of brandy.               _Gymmerwch wydriad o frandi._

  I do not drink spirits.               _Nid wyf yn yfed gwirod._

  Will you dine with me to-morrow?      _A giniawch chwi gyd a mi y_
                                          _fory?_

  I am sorry to say, I cannot.          _Mae yn ddrwg genyf ddweud_
                                          _nas gallaf._

  Why? what is the cause?               _Paham? beth ydyw yr achos?_

  I must go to Shrewsbury to-morrow     _Rhaid i mi fyned ir Amwythig_
    to meet my brother.                   _y fory i gyfarfod fy mrawd._

  Is he coming home?                    _A ydyw ef yn dyfod adre._

  Yes, for a short time.                _Ydyw am yehydig amser._

  It is time to go to rest.             _Mae hi yn bryd myned i orphwys._

  It is, I am getting sleepy.           _Ydyw y mae, yr wyf yn myned_
                                          _yn gysglyd._

  Good night, sir.                      _Nos da i chwi, syr._

  SALUTATIONS, &c.                      _CYFARCHIADAU, &c._

  Good afternoon, sir.                  _Prydnhawn da, syr._

  How are you to-day?                   _Sut yr ydych chwi heddyw?_

  I am very well, thank you.            _Yr wyf yn bur iach, diolch i_
                                          _chwi._

  How are the wife and children?        _Pa fodd mae 'r wraig a 'r_
                                          _plant?_

  They are all very well.               _Maent oll yn bur iach._

  Is your family well?                  _A ydyw eich teulu chwi yn_
                                          _iach?_

  They are all well except the          _Maent oll yn iach, oddi eithr_

  What ails him?                        _Beth sydd yn ei flino._

  How is your mother?                   _Sut y mae eich mam?_

  She is pretty well considering        _Mae hi yn lled dda, ac ystyried_
    her age.                              _ei hoed._

  How old is she?                       _Pa mor hen yw hi?_

  She is eighty since Christmas.        _Mae hi yn bedwar ugain er_
                                          _Nadolig._

  Is your father still living?          _A ydyw eich tad yn fyw eto?_

  No, he died last March.               _Nag ydyw, bu farw yn mis_
                                          _Mawrth diweddaf._

  Was he long ill?                      _A fu efe yn hir yn sal?_

  Yes, about two years.                 _Do, oddeutu dwy flynedd._

  You have had a great loss.            _Chwi a gawsoch golled fawr._

  Yes; but mother has had a             _Do, ond fy mam a gafodd fwy_
    greater loss.                         _o golled._

  Where was your father buried?         _Yn mha le y claddwyd eich_
                                          _tad?_

  He was buried at Wrexham.             _Claddwyd ef yn Ngwrecsam._

  What was his age?                     _Beth oed ei oedran?_

  Ninety.                               _Pedwar ugain a deg._

  He was very old.                      _Yr oedd yn bur hen._

  How are you this morning,             _Sut yr ydych chwi heddyw_
    sir?                                  _boreu, syr?_

  I am not well; neither have I         _Nid wyf yn iach, ac nid wyf_
    been well some time.                  _wedi bod yn iach er's peth_
                                          _amser._

  I am sorry to hear that.              _Mae'n ddrwg genyf glywed_
                                          _hyny._

  Where is your pain?                   _Yn mha le mae eich poen?_

  In my head.                           _Yn fy mhen._

  Have you been with a medical          _A fuoch chwi gyd a meddyg?_
    man?

  Yes; but the medicine does            _Do, ond nid ydyw y cyffyriau_
    me no good.                           _yn gwneuthwr daioni i mi._

  Perhaps the doctor does not           _Feallai nad ydyw y meddyg_
    understand your complaint.            _yn deall eich afiechyd._

  Perhaps so.                           _Feallai hyny._

  You had better try another.           _Gwell fyddai i chwi dreio un_
                                          _arall._

  Will you go with me?                  _A ewch chwi gyd a mi?_

  Yes, if you will stop until four      _Deuaf, os arhoswch tan bedwar_
    o'clock.                              _o'r gloch._

  Can't you go sooner?                  _Oni ellwch chwi fyned yn_
                                          _gynt?_

  No; I want to see my sister.          _Na allaf, mae arnaf eisiau_
                                          _gweled fy chwaer._

  Very well, call at the Harp           _Or goreu, gelwch yn Ngwesty'r_
    Inn.                                  _Delyn._

  Where were you yesterday?             _Pa le yr oeddych chwi ddoe?_

  At Chester.                           _Yn Nghaer._

  What news from there?                 _Pa newydd oddi yno?_

  Nothing at all of importance.         _Dim yn y byd o bwys._

  Did you see my brother there?         _A welsoch chwi fy mrawd yno?_

  Yes, I saw him at a distance;         _Do, gwelais ef o bell; yr oedd_
    he was very busy.                     _yn bur brysur._

  I expect him home next                _Yr wyf yn ei ddysgwil adre yr_
    week.                                 _wythnos nesaf._

  Not to stay at home.                  _Nid i aros gartref._

  No, only for a fortnight.             _Nage, dim ond am bythefnos._

  Is he in a good situation?            _A ydyw ef mewn sefyllfa dda?_

  Yes, a very good one.                 _Ydyw, un dda iawn._

  Have you much to do at Holyhead       _A oes genych lawer i wneud_

                                          _prydnhawn?_

  No, but little.                       _Nac oes, ond ychydig._

  Have you finished, sir?               _A orphenasoch chwi, syr?_

  Yes; but we must have a               _Do, ond rhaid i ni gael gwydriad_

    hand.                                 _wrth law._

  I will hire a pony.                   _Mi a logaf ferlyn._

  It will cost you seven shillings.     _Mi gostia i chwi saith swllt._

  Very well, here they are.             _O'r goreu, dyma nhw._

  Saddle him immediately.               _Cyfrwywch ef yn union._

  Which is the nearest road?            _Pa un yw y ffordd nesaf?_

  Across the hill.                      _Ar draws y bryn._

  Then, turn to your left.              _Wedi, hyny, trowch ar eich llaw
      aswy._

  Follow the brink of the river.        _Canlynwch lan yr afon._

  For how far?                          _Am ba mor bell._

  For a mile and a half.                _Am filltir a hanner._

  There is a beautiful prospect         _Mae yma olygfa hardd._
    here.

  Astonishing, what a variety!          _Rhyfedd, y fath amrywiaeth!_

  It is going to rain.                  _Mae hi yn myned i wlawio._

  We must make haste.                   _Mae yn rhaid i ni frysio._

  We shall be caught in the rain.       _Fe oddiwedda y gwlaw nyni._

  Will your horse trot?                 _A wna eich ceffyl duthio?_

  He will canter famously.              _Efe a garlama yn rhagorol._

  We shall not be long.                 _Ni byddwn yn hir._

  About half an hour.                   _Oddeutu hanner awr._

  That is a good pony.                  _Merlyn da yw hwna._

  Not so good, as the one I had         _Nid cystal, a'r hwn oedd genyf_
    yesterday.                            _ddoe._

  Take off your top coat.               _Tynwch eich côb._

  I am wet to the skin.                 _Yr wyf yn wlyb hyd y croen._

  And I am too.                         _A minnau hefyd._

  Put my clothes to dry.                _Rhowch fy nillad i sychu._

  I wish to see the monastery.          _Dymunwn weled y fynachlog._

  Which is the road to the old          _Pa un yw'r ffordd at yr hen_
    monastery?                            _fynachlog?_

  Go straight forward.                  _Ewch rhag eich blaen._

  Keep to the right hand.               _Cedwch ar y llaw ddehau._

  Make towards the grove yonder.        _Cyfeiriwch at y llwyn coed_
                                          _acw._

  Keep that white wall in view.         _Cedwch y wal wen acw mewn_
                                          _golwg._

  There is no finger post.              _Nid oes yna yr un mynegbost._

  Turn by the third milestone.          _Trowch wrth y drydedd gareg_
                                          _filltir._

  I shall be back in two hours.         _Mi a ddeuaf yn ol yn mhen dwy
      awr._

  I must be at home to-morrow           _Rhaid i mi fod gartref nos y
      fory._
    night.

  A horse will meet me at Conway.       _Fe ddaw ceffyl im cyfarfodd i
      Gonway._

  I shall reach home before midnight.   _Mi a gyrhaeddaf adre cyn_
                                          _hanner nos._

  I wish you a pleasant journey.        _Dymunaf i chwi siwrna gyssurus._

  Thank you, sir, for your kindness.    _Diolch i chwi, syr, am eich
      caredigrwydd._

  Make haste this way again.            _Brysiwch y ffordd yma eto._

  Perhaps I may come next year,         _Feallai y deuaf y flwyddyn nesaf,_
    but no sooner.                        _ond nid yn gynt._

  Remember me to Mrs. Jones             _Cofiwch fi at Mrs. Jones a'r_
    and all the family.                   _holl deulu._
