c. 1200, "to repair" (clothes, a tool, a building), "remove defects" (from something broken, defaced, deranged, or worn), from a shortened form of Old French amender "correct, set right, make better, improve" (see amend). Meaning "to put right, atone for (faults and errors), amend (one's life), repent" is from c. 1300. Intransitive sense of "to grow better, improve" is from late 14c. Related: Mended; mending.
early 14c., "recompense, reparation," a shortened form of amends. Sense of "a remedy, cure" (now obsolete) is from mid-14c., from mend (v.). Meaning "act of mending; a repaired hole or rip in fabric" is from 1888. Phrase on the mend "on the path to recovering from sickness, improving in condition" is attested by 1802.
"one who or that which repairs or mends," late 14c., agent noun from mend (v.). Originally especially "one who corrects what is wrong, a moral guide."
early 13c., amenden, "to free from faults, rectify," from Old French amender "correct, set right, make better, improve" (12c.), from Latin emendare "to correct, free from fault," from ex "out" (see ex-) + menda, mendum "fault, physical blemish; error," from PIE *mend- "physical defect, fault" (source also of Sanskrit minda "physical blemish," Old Irish mennar "stain, blemish," Welsh mann "sign, mark;" Hittite mant- "something harming").
The spelling with a- is unusual but early and also is found in Provençal and Italian. In English, the word has been supplanted in senses of "repair; cure" by its shortened offspring mend (v.). The meaning "to add to legislation" (ostensibly to correct or improve it) is recorded from 1777. Related: Amended; amending.
"given to lying, speaking falsely; having the characteristics of a lie, false, untrue," 1610s, from French mendacieux and directly from Latin mendacium "a lie, untruth, falsehood, fiction," from mendax (genitive mendacis) "lying, deceitful," from menda "fault, defect, carelessness in writing," from PIE root *mend- "physical defect, fault" (see amend (v.)). The sense evolution of Latin mendax was influenced by mentiri "to speak falsely, lie, deceive." Related: Mendaciously; mendaciousness.
"to cover with putty, mend or join with putty," 1734, from putty (n.). Related: Puttied; puttying.
"practicing beggary, living by alms or doles" (in reference to orders of friars), late 15c., mendicaunt, from Latin mendicantem (nominative mendicans) present participle of mendicare "to beg, ask alms," from mendicus "beggar," originally "cripple" (connection via cripples who must beg), from menda "fault, physical defect," from PIE root *mend- "physical defect, fault" (see amend (v.)).
Meaning "reduced to beggary, begging" is from 1610s. The older word in Middle English in relation to religious orders was mendinant (mid-14c.), from Old French mendinant, present participle of mendiner "to beg," from the same Latin source. The mendicant orders (freurs mendicantes or begging friars, principally the Franciscans, the Carmelites, and the Augustinians) were those religious orders which originally depended for support on the alms they received.
