Common mistakes

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

Using early on before a noun phrase

Early on usually stands alone rather than directly modifying a noun phrase.

✕ Early on the year, sales improved. ✓ Early in the year, sales improved.

Confusing early for with early in

Early for refers to schedule timing, not a period of time.

✕ He arrived early in the interview. ✓ He arrived early for the interview.

Omitting the object after early for

Early for normally needs the event or appointment.

✕ She was early for. ✓ She was early for the meeting.
