Learn French: Tu es un homme.

In French, every noun is either masculine or feminine. The word for man, homme, is masculine, so we must use the masculine word for a or an, which is un. If we were talking about a woman (femme), we would use the feminine word une.

Why does it sound like the n in un connects to the word homme?

The letter h at the beginning of homme is silent. Because the word starts with a vowel sound, the normally silent n at the end of un is pronounced and connects to it. This connection is called a liaison, and it makes the two words flow together to sound like un nomme.

Why is the verb spelled es with an s at the end?

This is the verb être, which means to be. In French, verb endings change depending on who you are talking about. When using the informal you (tu), this verb is always spelled es. The s at the end is completely silent.

Could I use vous instead of tu in this sentence?

Yes! Both tu and vous mean you. Tu is used when talking to one person you know well, like a friend or family member. If you were speaking to an adult you do not know well or want to show formal respect to, you would say Vous êtes un homme.
