ConnectionVる + わけにはいかない

How to use it

States that one CANNOT do A for social or psychological reasons (even though it is physically possible).

  • 「Vるわけにはいかない」 = cannot do A (due to responsibility, propriety, or social circumstance).
  • Different from 「~できない」 (lack of ability): this pattern means "able to do it but NOT ALLOWED to, morally speaking".
  • The opposite is 「~ないわけにはいかない」 (obliged to do) — pay attention to where 「ない」 is placed.

Examples

  • It is an important meeting, so I cannot take the day off.

  • Since I promised, I cannot quit halfway.

  • Tomorrow is an important meeting, so I cannot take the day off.

Keep in mind

  • Not a lack of ability, but a social/psychological constraint.
  • Be careful to distinguish it from the form with 「ない」 in front.

Common mistakes

  • Wrong休(やす)まないわけにはいかない。

    Correct休(やす)むわけにはいかない。

    The meaning "cannot do" uses Vる + わけにはいかない.

  • Wrong重(おも)すぎて、この荷物(にもつ)を持(も)つわけにはいかない。

    It's too heavy, I can't carry this parcel.

    Correct重(おも)すぎて、この荷物(にもつ)は持(も)てない。

    Not having enough strength is a matter of ABILITY, so use 「持てない」.

  • Wrong休(やす)まないわけにはいかないから、会議(かいぎ)に出(で)る。

    I can't take the day off, so I have to attend the meeting.

    Correct休(やす)むわけにはいかないから、会議(かいぎ)に出(で)る。

    Wrong polarity: "cannot take a day off" is 「休むわけにはいかない」.

Exam tips

  • 「Vるわけにはいかない」 = cannot (due to propriety/circumstance), different from 「できない」 (lack of ability).
