Today’s Grammar Point: ~べき/~べきだ/~べきじゃない/~べきではない
Today’s grammar point is ~べき. べき derives of an old auxiliary verb ~べし which is similar to the English auxiliary verb “should” and ~べき describes a natural sequence, an obligation, appropriateness and/or a schedule. It only follows a dictionary form verb and if the meaning to convey is in the negative, ~べきじゃない or ~べきではない should be used. If the verb ends in する, the last る is often omitted.
Connection
- [affirmative plain form verb] べき + だ/です (affirmative sentence ending)
- [affirmative plain form verb] べき + じゃ/では + ない (negative sentence ending)
- [affirmative plain form verb] べき + [noun] (form a contact clause)
