Middle English mēten, from Old English metan "to find, find out; fall in with, encounter, come into the same place with; obtain," from Proto-Germanic *motjanan (source also of Old Norse mæta, Old Frisian meta, Old Saxon motian "to meet," Gothic gamotijan), from PIE root *mod- "to meet, assemble." Related to Old English gemot "meeting."
By c. 1300, of things, "to come into physical contact with, join by touching or uniting with;" also, of persons, "come together by approaching from the opposite direction; come into collision with, combat." Abstractly, "to come upon, encounter (as in meet with approval, meet one's destiny) by late 14c. Sense of "come into conformity with, be or act in agreement with" (as in meet expectations) is by 1690s.
Intransitive sense, of people, "to come together" is from mid-14c.; of members of an organized body or society, "to assemble," by 1520s. Related: Met; meeting. To meet (someone) halfway in the figurative sense "make mutual and equal concessions to" is from 1620s. Well met as a salutation of compliment is by mid-15c.
c. 1300, mēte, "having the right shape or size," from Old English gemæte, Anglian *gemete, "suitable, having the same dimensions," from Proto-Germanic *ga-mætijaz (source also of Old Norse mætr, Old High German gimagi, German gemäß "suitable"), from collective prefix *ga- + PIE root *med- "take appropriate measures." The formation is the same as that of commensurate. Meaning "proper, appropriate" is from early 14c.; that of "fit (to do something)" is from late 14c.
The mountain sheep are sweeter,
But the valley sheep are fatter;
We therefore deem'd it meeter
To carry off the latter.
[Thomas Love Peacock, from "The War-song of Dinas Vawr"]
1831 in the sporting sense, "a gathering of huntsmen for fox-hunting," from meet (v.). Later of bicyclists gathering for a ride, etc.
masc. proper name, from Old English Mælwine, literally "friend of the council," from mæl "council," from Proto-Germanic *mathla- (from PIE *mod- "to meet, assemble;" see meet (v.)) + wine "friend" (related to winnan "to strive, struggle, fight;" see win (v.)).
"an action of coming together," Old English meting "assembly," verbal noun from meet (v.). Specific meaning "gathering of people for discussion, etc." is from 1510s. In 17c., in England and Ireland it was applied generally to worship assemblies of nonconformists, but this now is retained mostly by Quakers. In the early U.S., especially in rural districts, it was applied to any assemblage for religious worship.
early 12c., from Old English gemot "meeting, formal assembly" (especially of freemen, to discuss community affairs or mete justice), "society, assembly, council," from Proto-Germanic *ga-motan (compare Old Low Frankish muot "encounter," Middle Dutch moet, Middle High German muoz), from collective prefix *ga- + *motan (see meet (v.)). In early 15c. awful moot was used for "the Last Judgment."
also help-meet, a ghost word from the 1611 "King James" translation of the Bible, in which it was at first a two-word noun-adjective phrase translating Latin adjutorium simile sibi [Genesis ii.18] as "an help meet for him," and meaning literally "a helper like himself."
Robert Alter ("The Five Books of Moses," 2004) suggests sustainer beside him as the closest possible in English to the original:
The Hebrew 'ezer kenegdo (King James Version "help meet") is notoriously difficult to translate. The second term means "alongside him," "opposite him," "a counterpart to him." "Help" is too weak because it suggests a mere auxiliary function, whereas 'ezer elsewhere connotes active intervention on behalf of someone, especially in military contexts, as often in Psalms.
