Learn Italian: I brusii dei clienti mi disturbano. - The murmurs of the customers bother me.

It depends on where the stress falls in the singular word. In brusio, the stress is on the 'i' (bru-SÌ-o). When a masculine noun ends in a stressed -io, the plural keeps both vowels to become -ii. If the 'i' is unstressed in the singular (like in bacio or orologio), the plural drops the extra vowel and ends in a single -i.

How do you pronounce the double 'i' at the end of brusii?

You pronounce both vowels, which creates an elongated 'ee' sound. The spoken stress remains exactly where it was in the singular, so it is pronounced bru-SÌ-i.

What exact kind of noise does brusio describe?

Brusio specifically describes a continuous, indistinct background noise. It is most commonly used for the low murmur or buzzing of a crowd (like in a busy restaurant or theater), but it can also be used for the humming of insects or the rustling of leaves.

Why do we use dei clienti instead of just di clienti here?
