English highway-sentence

Modals+have+past participle

We use the pattern modal verb + have + past participle to make a guess about something that probably happened in the past.

e.g. Tom must have eaten my pudding.

(= I am quite sure Tom has eaten my pudding.)

e.g. You could have told me before you left.

(= It'd be better if you had told me before you left.)
