To give counsel or advice to someone; an archaic term meaning to advise or counsel.
From Middle English accounselen, composed of prefix ac- (to) + counsel. This Old French-influenced formation was used in Early Modern English but became obsolete as 'counsel' alone became preferred.
This word shows how English used to attach prefixes like 'ac-' to verbs to intensify meaning, a pattern we mostly abandoned—leaving ghost words like this one frozen in historical texts.
