Today’s Question


How likely is my father to be in Tokyo now?

Today’s Grammar Point:  ~たはず

~はず is used to describe a natural consequence (is supposed to, should) or a plan (is scheduled to) but when はず is used with a たform verb (past plain form), it often describes an action which should have taken place but actually didn’t and ~たはず implies the speaker’s surprise or regret. ~たはず can also be used when the speaker is making a guess on somebody else’s action in the past which the speaker does not know for sure if it actually happened or not.


  • [たform verb] + はず(だ/です)
    たform verb is the past plain form of a verb
