فكل8 افتكل فِى فِعْلِهِ i. q. اِحْتَفَلَ [He strove, laboured, or exerted himself, &c., in his doing]; (IAar, O, K;) said of a man. (IAar, O.) أَفْكَلُ A tremour, (S, O, K,) from cold or from fear: (S:) hence, in a trad., أَخَذَنِى أَفْكَلُ [A tremour seized me]: (S, * O:) and in another, فَبَاتَ وَلَهُ أَفْكَلُ [And he passed the night having a tremour, or shivering]: (O:) thus used, as indeterminate, it is perfectly decl.; but if used as a [proper] name of a man, it is imperfectly decl. because determinate and also of the measure of a verb: (S, O:) some say, (IF, O,) no verb is formed from it; (IF, S, O;) but such is not the case, for they said رَجُلٌ مَفْكُولٌ [which shows that it had a verb though none is known to have been in use]. (IF, O.) [أَخَذَتْ بِى نَاقَتِى أَفْكَلًا مِنَ السَّيْرِ is a saying mentioned in the O and K, (in the former as from Ibn-'Abbád,) but the meaning is not expl., nor indicated by the context, in either of them; and the strangeness of its phraseology convinces me that it presents a mistranscription: I believe that the first word is mistranscribed for أَحْدَثَتْ, and, consequently, that the meaning is, My she-camel produced in me a tremour arising from the rate of journeying: some copies of the K, as is stated in the TA, for مِنَ السَّيْرِ, have من السَّبْقِ, from the outstripping.] b2:  Also The [bird commonly called] شِقِرَّاق [generally meaning the green wood-pecker]; (O, K;) because they regard it as of evil omen; so that when it presents itself to them, they are frightened at it, and tremble. (O.) A2:  And A company, or collective body, of men: one says, جَاؤُوا بِأَفْكَلِهِمْ They came with their company [i. e. all together]. (Ibn-'Abbád, O, K.) أَفَاكِيلُ [is app. a pl. thereof, and, as such,] signifies أَفْوَاجٌ [pl. of فَوْجٌ, q. v.]: thus in the phrase أَفَاكِيلُ مِنْ كَذَا [app. meaning Multitudes of such a kind of thing]: (K:) [or] thus in the saying, mentioned by Ibn-'Abbád, عِنْدَهُ أَفَاكِيلُ مِنْ كَلَامٍ [app. meaning He has multitudes of sayings, or words; for كَلَامٌ (q. v.) is used in a pl. sense as well as in a sing. sense]. (O. [The difference of these two exs. in respect of the last word suggests that there may be in one of them a mistranscription.]) مَفْكُولٌ [the pass. part. n. of a verb which is not mentioned,] Affected with a tremour. (IF, O, K, TA. [See أَفْكَلُ, first sentence.])
