How to form it

  • Verb (て-form) + いく / いきます
  • Movement: 買っていく, 持っていく

Explanation

Shows movement away from the speaker or the continuing of a change into the future.

For movement it means doing something and then going. For change it shows a continuing development from now on.

  • Using ～ていく for a change that has already finished.
