Past modals let you talk about the past without being 100% factual: you can make deductions, express possibility, criticise decisions or regret actions.I past modals ti permettono di parlare del passato non solo come fatto, ma anche come deduzione, possibilità, critica o rimpianto.

Strong deductionDeduzione forte

must have + past participle

Italian trap: Non usare had to per rimpianti. I should have called = avrei dovuto chiamare.
