mid-14c., "a rebuke, blame, censure;" also "object of scorn or contempt;" c. 1400, as "disgrace, state of disgrace," from Old French reproche "blame, shame, disgrace" (12c.), from reprochier "to blame, bring up against," said by some French etymologists to be from Vulgar Latin *repropiare, from Latin re- "opposite of" + prope "near" (see propinquity), with suggestions of "bring near to" as in modern "get in (someone's) face." But others would have it from *reprobicare, from Latin reprobus/reprobare (see reprobate (adj.)).
mid-14c., reprochen "to rebuke, reproach," from Anglo-French repruchier, Old French reprochier "upbraid, blame, accuse, speak ill of," from reproche (see reproach (n.)). Related: Reproached; reproaching.
To reproach a person is to lay blame upon him in direct address, and with feeling, to endeavor to shame him with what he has done. [Century Dictionary]
