Questions & Answers about Cette tour est la moins haute.
Why is it la moins instead of le moins?
Could I say Cette tour est la tour la moins haute?
Do I make a liaison between the 's' in moins and the word haute?
No, you don't. The word haute starts with what is called an aspirated 'h' in French. Even though the 'h' is silent, it acts like a consonant and blocks liaisons. So, you do not pronounce a 'z' sound between moins and haute.
