遂に means "finally", "at last": after a long wait, a long effort or a long
build-up, the thing happens. It is an adverb, placed at the start of the
clause or just before the verb, and the verb is usually in the past. It is
mostly written in kana, ; the kanji is the formal spelling.
。
My dream finally came true.
いちれい10、。
After ten years of effort, he finally won the championship.
。
The day has finally come.
The result can be good or bad. 遂に only says it is the end point of
something that has been coming for a long time.
。
That old building was finally demolished.
Never happened in the end
With a negative verb, 遂に says that what everyone waited for did not happen,
right to the end.
。
He never showed up in the end.
、。
I kept waiting, but he never came.
遂に, とうとう or やっと
means the same and takes good or bad results and a negative
verb as well. 遂に sounds more dramatic – headlines, announcements, a
climax in a story – and とうとう is the everyday word.
is only for a result you wanted, with relief that it has come,
so it does not fit a thing breaking down.
