A mixed conditional is a conditional sentence that mixes the past, present or future.

The most common mixed conditional is a third / second conditional (unreal past / present).

This is when we talk about something in the past and its result in the present.

• If I had gone to bed early (last night), I wouldn't be tired (now).
• If you had called Lucy (yesterday), she would know about the meeting (now).
• She would be happier (now) if she hadn't taken that job (last year).
