Common mistakes

Some combinations appear in real text but do not mean what learners often assume.

Using complete with for deadlines

Use by for deadlines, not with.

✕ The task must be complete with Monday. ✓ The task must be complete by Monday.

Confusing complete and completed

Complete is often an adjective; completed is the past participle verb form.

✕ The team complete the form yesterday. ✓ The team completed the form yesterday.

Using complete at as a fixed pattern

At usually adds time or place information rather than following complete directly.

✕ The project is complete at the requirements. ✓ The project is complete in terms of the requirements.
