Forms ask you to write information in their spaces.

The idea

Fill in means complete a form or write information in a space. With a noun, say fill in the form or fill the form in. A pronoun goes between the two parts: fill it in. The past is filled in.

Examples

  • Please fill in the registration form.
  • I filled in my address carefully.
  • Can you fill the form in today?
  • We filled it in at the desk.
  • The visitor is filling in the date.
  • She forgot to fill in the last box.

Watch out

Do not say fill in it: a pronoun must go between the verb and particle. This lesson focuses on forms, not replacing a person.
