How to use it

Doing the main activity A while also taking the chance to do B; both activities happen on the same trip/occasion.

  • 「~がてら」 = while doing A, also take the opportunity to do B: two activities combined into one trip/occasion.
  • The preceding clause is usually an activity involving MOVEMENT or an existing activity (散歩・買い物・見舞い).
  • Close to 「~ついでに」 (colloquial, more common); 「がてら」 is somewhat literary, and the following clause is usually in the same direction as the preceding one.

Examples

  • While out for a walk, I strolled over to the neighborhood park.

  • On my shopping trip, I dropped by a friend’s place.

Keep in mind

  • A noun attaches directly; a verb uses the masu-stem.
  • Both activities must be doable on the same occasion.

Common mistakes

  • Wrong寝(ね)るがてら、本(ほん)を読(よ)んだ。

    I read a book before going to sleep.

    Correct寝(ね)る前(まえ)に本(ほん)を読(よ)んだ。

    「がてら」 combines two activities into ONE occasion/trip; it's not used for activities that can't be combined.

  • Wrong買(か)い物(もの)するがてら、友達(ともだち)に会(あ)った。

    While out shopping, I also ran into a friend.

    Correct買(か)い物(もの)がてら、友達(ともだち)に会(あ)った。

    A noun attaches directly; a verb must use the MASU-STEM (買い物しがてら), not the dictionary form.

Exam tips

  • 「がてら」 = doing something along the way (one occasion); nouns attach directly, verbs use the masu-stem.
