〜て以来
JLPT N3:ever since
"Ever since X": a state or situation has continued from a past event up to now.
How to form it
- Put the verb in the て-form and add 以来: 日本に来て以来.
- Nouns take 以来 directly: 卒業以来 (since graduation).
- The second half describes something that has continued, not a single event.
Examples
日本に来て以来、ずっとここに住んでいる。
I've lived here ever since I came to Japan.
入院して以来、運動していない。
I haven't exercised since I was in hospital.
Notes
- It is more formal than てから, and stresses the whole period since.
Common mistakes
- Using it for a recent, short span. Say 昨日帰ってから, not 帰って以来.
Similar meaning
- 〜てからafter doing
"After" or "since"; everyday.
