とっくに + Verb (past tense)

[Long ago / Already (a long time ago)]

Connection: とっくに + Verb (past tense)

Usage: An adverb meaning that something happened a long time ago, or was completed well before the expected time. Carries a nuance of "it's been done ages ago" — often implying slight surprise, impatience, or emphasis that the listener should already know. Colloquial but widely used.

Similar expressions:

• もう = already (neutral)
• すでに = already (formal)
• とうに = long ago (slightly more formal than とっくに)

Examples:

そんなことはとっくに知っていたよ。(I knew that ages ago.)

宿題はとっくに終わったよ。(I finished my homework a long time ago.)

電車はとっくに出発してしまった。(The train left a long time ago.)
