-ㄴ/은 지… 되다 It’s Been… Since
August 25, 2009 by tailieutienghan
This grammatical pattern is used to mark the amount of time since one has or has not done a certain activity. It is used in conjunction with action verbs and time words and can be translated as “It's been (time) since…”
Mood, tense, negation, and politeness levels are expressed in the final verb 되다 (doeda).
– Action Verb stem + -ㄴ/은 지 + time word + 되다
자다 (jada) – to sleep
자 (ja) – verb stem
자 + ㄴ 지 + (time word) + 되다
잔 지 3일 됐어. (jan ji 3il doaesseo.) – It's been three days since I've slept.
– 여기에서 일한 지 3달 됐어요. (It's been three months since I started working here.)
– 한국에 온 지 오래 됐어요. (It's been a long time since I came to Korea.)
– 담배 끊은 지 1주일 됐어요. (It's been three weeks since I quit smoking.)
1.The time word used in this construction must indicate a length of time either specific (i.e. 3 hours, 2 days, 12 years) or non-specific (i.e. a while, a few days). The time word cannot be a point in time (3 o'clock, April 2nd).
2.Since this construction is used to express an amount of time since one has done something, the final verb (되다) is almost always conjugated into the past tense.
