c. 1500, objurgacioun, "act of scolding or rebuking," from Old French objurgacion (15c.) and directly from Latin obiurgationem (nominative obiurgatio) "a chiding, reproving, reproof," noun of action from past-participle stem of obiurgare (see objurgate). Related: Objurgate; objurgative; objurgatory.
late 12c., "scold, nag, rail," originally intransitive, from Old English cidan "to contend, quarrel, complain." Not found outside Old English (though Liberman says it is "probably related to OHG *kîdal 'wedge,'" with a sense evolution from "brandishing sticks" to "scold, reprove").
Originally a weak verb, later strong constructions are by influence of ride/rode, etc. Past tense, past participle can be chided or chid or even (past participle) chidden (Shakespeare used it); present participle is chiding.
