Questions & Answers about Questa lettera ha quaranta parole.
Does the number quaranta change its ending to match the plural noun parole?
No, it doesn't. In Italian, cardinal numbers from two upwards are invariable. This means their endings never change to match the gender or number of the noun they describe. So it is always quaranta, never "quarante", even though parole is a feminine plural noun.
