Learn Turkish: Eğer o adam suçsuz olsaydı, beraat etmeliydi. - If that man had been innocent, he should have been acquitted.

It combines the verb beraat etmek (to be acquitted) with the obligation suffix -meli (must/should), the buffer letter -y-, and the past tense suffix -di. Together, -meliydi means "should have done something", showing an unfulfilled past obligation.

The English translation says "be acquitted", but is beraat etmek an active verb?

Yes, it takes an active form in Turkish. The Arabic loanword beraat means "acquittal" or "clearance from guilt". So beraat etmek translates to the passive "to be acquitted" in English. If a judge acquitted someone, you would use the causative form beraat ettirmek.

Let's break down olsaydı. Why are both -sa and -dı used here?

The verb olmak (to be) takes the conditional suffix -sa (if) and the past tense suffix -dı. Together, -saydı creates an unreal past condition, meaning "if he had been". This pairs perfectly with the unfulfilled obligation in the second half of the sentence.

How is the word suçsuz formed?

It comes from the noun suç, meaning "crime", "fault", or "guilt". Adding the suffix -suz (meaning "without" or "-less") creates suçsuz, literally meaning "guiltless" or "innocent".
