You’re writing about your childhood. You want to describe two things:

  1. You visited your grandparents every weekend.

  2. You lived in the countryside.

Write one sentence using both would and used to correctly — and explain why each one is used where it is.

"I would visit my grandparents every weekend when I used to live in the countryside."

 Explanation:

  • “Would” is used for the repeated action (visit).

  • “Used to” is used for the past state (live).

  • This shows how different modals are needed depending on whether you're describing a habitual action or a state of being.
