poetry (n.)youdaoicibaDictYouDict[poetry 词源字典]
late 14c., "poetry; a poem; ancient literature; poetical works, fables, or tales," from Old French poetrie (13c.), and perhaps directly from Medieval Latin poetria (c.650), from Latin poeta (see poet). In classical Latin, poetria meant "poetess."
... I decided not to tell lies in verse. Not to feign any emotion that I did not feel; not to pretend to believe in optimism or pessimism, or unreversible progress; not to say anything because it was popular, or generally accepted, or fashionable in intellectual circles, unless I myself believed it; and not to believe easily. [Robinson Jeffers (1887-1962), forward to "Selected Poems"]


Poetry -- meaning the aggregate of instances from which the idea of poetry is deduced by every new poet -- has been increasingly enlarged for many centuries. The instances are numerous, varied and contradictory as instances of love; but just as 'love' is a word of powerful enough magic to make the true lover forget all its baser and falser, usages, so is 'poetry' for the true poet. [Robert Graves, "The White Goddess"]
Figurative use from 1660s. Old English had metergeweorc "verse," metercræft "art of versification." Modern English lacks a true verb form in this group of words, though poeticize (1804), poetize (1580s, from French poétiser), and poetrize (c. 1600) have been tried. Poetry in motion (1826) perhaps is from poetry of motion (1813) "dance" (also poetry of the foot, 1660s).[poetry etymology, poetry origin, 英语词源]
