what does the word meter mean in poetry
Metre (poetry) In poetry, metre is the basic rhythmic structure of a verse or lines in verse. Many traditional verse forms prescribe a specific verse metre, or a certain set of metres alternating in a particular order. The study and the actual use of metres and forms of versification are both known as prosody. (Within linguistics, "prosody" is used in a more general sense that includes not only poetic metre but also the rhythmic aspects of prose, whether formal or informal, that vary from language to language, and sometimes between poetic traditions.)
To Autumn The rhyme of "To Autumn" follows a pattern of starting each stanza with an ABAB pattern which is followed by rhyme scheme of CDEDCCE in the first verse and CDECDDE in the second and third stanzas.[45] In each case, there is a couplet before the final line. Some of the language of "To Autumn" resembles phrases found in earlier poems with similarities to Endymion, Sleep and Poetry, and Calidore.[50] Keats characteristically uses monosyllabic words such as "...how to load and bless with fruit the vines that round the thatch-eves run." The words are weighted by the emphasis of bilabial consonants (b, m, p), with lines like "...for Summer has o'er-brimm'd their clammy cells." There is also an emphasis on long vowels which control the flow of the poem, giving it a slow measured pace: "...while barred clouds bloom the soft dying day".[45]
