Prepositions after adjectives

Unlikely to, in, for, of, or at?

Unlikely is normally followed by to plus a verb. Other prepositions usually belong to separate phrases about place, time, or topic.

Use to before the verb.

✕ She is unlikely win. ✓ She is unlikely to win.

Using unlikely at as the main pattern

At is not normally selected by unlikely.

Confusing unlikely of and unlikely for

Of comments on behaviour; for introduces the person connected to the action.
