me (pron.)youdaoicibaDictYouDict
Old English me (dative), me, mec (accusative); oblique cases of I, from Proto-Germanic *meke (accusative), *mes (dative), cognates: Old Frisian mi/mir, Old Saxon mi, Middle Dutch mi, Dutch mij, Old High German mih/mir, German mich/mir, Old Norse mik/mer, Gothic mik/mis; from PIE root *me-, oblique form of the personal pronoun of the first person singular (nominative *eg; see I); cognates: Sanskrit, Avestan mam, Greek eme, Latin me, mihi, Old Irish me, Welsh mi "me," Old Church Slavonic me, Hittite ammuk.

Erroneous or vulgar use for nominative (such as it is me) attested from c. 1500. Dative preserved in obsolete meseems, methinks and expressions such as sing me a song ("dative of interest"). Reflexively, "myself, for myself, to myself" from late Old English.

"fermented honey drink," Old English medu, from Proto-Germanic *meduz (cognates: Old Norse mjöðr, Danish mjød, Old Frisian and Middle Dutch mede, Old High German metu, German Met "mead"), from PIE root *medhu- "honey, sweet drink" (cognates: Sanskrit madhu "sweet, sweet drink, wine, honey," Greek methy "wine," Old Church Slavonic medu, Lithuanian medus "honey," Old Irish mid, Welsh medd, Breton mez "mead"). Synonymous but unrelated early Middle English meþeglin yielded Chaucer's meeth.

Now only archaic or poetic.

late 14c. (late 12c. as a surname), "lean, thin, emaciated" (of persons or animals), from Old French megre, maigre "thin" (12c.), from Latin macrum (nominative macer) "lean, thin" (source of Spanish, Portuguese, and Italian magro), from PIE *makro- (see macro-). Of material things (land, food, etc.) from early 15c. Cognate Germanic words (Old Norse magr "thin," Old High German magar, German mager, Middle Dutch magher, Dutch mager, Old English mæger) come directly from the PIE root via Proto-Germanic *magras and are not from Latin.
meagerly (adv.)youdaoicibaDictYouDict
also meagrely, 1580s, from meager + -ly (2).
meagerness (n.)youdaoicibaDictYouDict
also meagreness, early 15c., from meager + -ness.

meal (n.1)youdaoicibaDictYouDict
"food; time for eating," c. 1200 (perhaps late Old English), mel "appointed time for eating," also "a meal, feast," from Old English mæl "fixed time, occasion, a meal," from Proto-Germanic *mæla- (cognates: Old Frisian mel "time;" Middle Dutch mael, Dutch maal "time, meal;" Old Norse mal "measure, time, meal;" German Mal "time," Mahl "meal;" Gothic mel "time, hour"), from PIE *me-lo-, from root *me- "to measure" (see meter (n.2)). Original sense of "time" is preserved in piecemeal. Meals-on-wheels attested from 1961. Meal ticket first attested 1870 in literal sense of "ticket of admission to a dining hall;" figurative sense of "source of income or livelihood" is from 1899.
meal (n.2)youdaoicibaDictYouDict
"edible ground grain," Old English melu "meal, flour," from Proto-Germanic *melwan "grind" (cognates: Old Frisian mele "meal," Old Saxon melo, Middle Dutch mele, Dutch meel, Old High German melo, German Mehl, Old Norse mjöl "meal;" Old Saxon, Old High German, Gothic malan "to grind," German mahlen), from PIE root *mel- (1) "soft" (see mallet).
mealtime (n.)youdaoicibaDictYouDict
also meal-time, late 12c., from meal (n.1) + time (n.). Etymologically, a tautology.
mealy (adj.)youdaoicibaDictYouDict
"resembling or consisting of meal," 1530s, from meal (n.2) + -y (2). Related: Mealiness.
mealy-mouthed (adj.)youdaoicibaDictYouDict
"afraid to say what one really thinks," 1570s; first element perhaps from Old English milisc "sweet," from Proto-Germanic *meduz "honey" (see mead (n.1)), which suits the sense, but if the Old English word did not survive long enough to be the source of this, perhaps the first element is from meal (n.2) on notion of the "softness" of ground flour (compare Middle English melishe (adj.) "friable, loose," used of soils).
mean (v.1)youdaoicibaDictYouDict
"intend, have in mind," Old English mænan "to mean, intend, signify; tell, say; complain, lament," from West Germanic *mainijan (cognates: Old Frisian mena "to signify," Old Saxon menian "to intend, signify, make known," Dutch menen, German meinen "think, suppose, be of the opinion"), from PIE *meino- "opinion, intent" (cognates: Old Church Slavonic meniti "to think, have an opinion," Old Irish mian "wish, desire," Welsh mwyn "enjoyment"), perhaps from root *men- "think" (see mind (n.)). Conversational question you know what I mean? attested by 1834.
