indicate

• 指示する；指摘する；予兆する；象徴する

ラテン語のindicare（指し示す、示す）から、in-（入る、作る）、-dic（指し示す、言う）に由来し、語源的にはdigit（数字）、index（索引）と同じ。

indicate

indicate: [17] Like index, indicate has its origins in the Latin stem *dik- ‘point out’. In this case the base form was the verbal derivative dicāre ‘proclaim’ (ultimate ancestor also of English abdicate [16], dedicate [15] and predicate [16]), which with the addition of the prefix inproduced indicāre ‘show’ – which English adopted as indicate.

First cousin of Latin dicāre was dīcere ‘say’ (source of English diction, dictionary, etc). Addition of the prefix in- to this produced indīcere ‘proclaim’, which formed the basis of Vulgar Latin *indictāre ‘declare, dictate’. This has given English two separate verbs: via Old French enditier the now archaic indite [14]; and via Anglo-Norman enditer, with subsequent latinization of the spelling, indict [14].
=> abdicate, dedicate, predicate
