Questions & Answers about Penso che Santo Stefano abbia un gran campanile.
Why is it Santo Stefano and not San Stefano?
Why does grande become gran in this sentence?
Does gran campanile mean 'great bell tower' or 'large bell tower'?
Why do we use abbia here instead of ha?
Abbia is the present subjunctive form of avere. We use the subjunctive mood here because the sentence starts with penso che (I think that), which expresses a personal opinion or thought rather than an objective fact.
