FAQs
What is the difference with 기 전에 and 후에?
기 전에 means “before (doing something),” while 후에 means “after (doing something).”
They are used to indicate the time sequence of actions.
Can I use 기 전에, 후에 with verbs and nouns?
기 전에 is only used with verbs, while 후에 can be used with both verbs and nouns.
When using 후에 with a noun, you don’t need the 기 form.
How do I use 기 전에 and 후에 with past and future tenses?
The verb before 기 전에 is always in its base form, but the main verb in the sentence can be conjugated in past, present, or future tense.
With 후에, the verb before it is also in its base form, but the main verb follows normal tense conjugation rules.
Is there a difference between 후에 and 다음에?
Both can mean “after,” but 후에 is slightly more formal, while 다음에 is often used in casual speech to mean “next time” or “after that.”
Can I use 기 전에 and 후에 in the same sentence?
Yes!
You can use both to describe sequential events, like:
밥을 먹기 전에 손을 씻고, 먹은 후에 이를 닦아요.
