Learn Italian: Tutte le giraffe dello zoo sono alte. - All the giraffes in the zoo are tall.

In Italian, when you use the word for "all" (tutto, tutta, tutti, or tutte) followed by a noun, you must include the definite article (the word for "the"). Because giraffe is a feminine plural noun, it takes the article le, giving us the structure Tutte le giraffe.

Why do Tutte and alte both end in "-e"?

They both need to match the gender and number of the noun they describe, which is giraffe. Since giraffe is feminine plural, the quantifier tutto changes its ending to become tutte, and the adjective alto (tall) changes to alte.

Why is it dello zoo instead of just del zoo?

Dello is a combined word made from the preposition di (of) and the definite article lo (the). We must use lo instead of il because the word zoo starts with the letter 'z'. When you combine di + lo, it always becomes dello.

Why use dello here if the English translation says "in the zoo"? Wouldn't "in the" be nello?
