Questions & Answers about I suoi vicini sono molto simpatici.
Why do we use i suoi here? Could this also mean "her neighbors"?
Yes! In Italian, possessive adjectives agree with the thing being possessed, not the owner. Because vicini (neighbors) is a masculine plural noun, you must use the masculine plural possessive i suoi. Without more context, i suoi vicini can mean "his neighbors," "her neighbors," or even formal "your neighbors."
Why is there an i before suoi? We don't say "the his neighbors" in English.
In Italian, you almost always need a definite article (like il, la, i, or le) right before a possessive adjective. Since the word for "the neighbors" is i vicini, you simply insert the possessive in the middle to get i suoi vicini.
Does simpatici mean "sympathetic"?
No, this is a very common "false friend"! Simpatico (singular) or simpatici (plural) means "nice," "pleasant," or "likable" when talking about a person's character. If you want to say someone is sympathetic or understanding, you would use a word like comprensivo.
How does the adjective simpatici match the noun, and how is it pronounced?
