Questions & Answers about Não fosse o instinto dele, não teríamos escapado.
Why is there no se (if) at the beginning of this sentence?
This is a special structure. By starting directly with Não fosse (the imperfect subjunctive of the verb ser), we create an inverted conditional meaning 'Were it not for' or 'If it had not been for'. It is an elegant alternative to saying Se não fosse.
Why does Não fosse pair with teríamos escapado (conditional perfect)? Shouldn't an unreal past situation use the past perfect subjunctive?
Great observation! Normally, past unreal situations require the past perfect subjunctive (like Se não tivesse sido...). However, the fixed expression não fosse (or não fossem) + noun is a common exception. It is frequently used to mean 'If it hadn't been for' regarding past events, and it pairs perfectly with the conditional perfect here.
Could we rearrange this to put the subject first, like O instinto dele não fosse...?
Why use dele instead of seu for 'his instinct'?
