Expert writing Tips

Best practice

When using "filled it in", ensure the context clearly indicates what "it" refers to. For example, "I filled it in" is less clear than "I filled in the application form".

Common error

Avoid using "filled it in" without a clear antecedent for "it". Vague references can confuse the reader. Instead, explicitly state what you are filling in, like "filled in the form" or "filled in the missing information".
