Learn French: Nous avons un appartement spacieux.

Avons means "have" when paired with nous (we). It is the "nous" form of the irregular verb avoir (to have). Because avoir is highly irregular, plural forms like avons, avez (you have), and ont (they have) just need to be memorized.

How do you pronounce the spaces between Nous, avons, and un?

You connect them! Normally, the S at the end of Nous and avons is silent. But because the next words start with vowels, you pronounce the S as a "Z" sound that jumps to the beginning of the next word. This linking is called a "liaison". Spoken aloud, the beginning of this sentence sounds like "Noo zah-vohn zun".

Why is the word order appartement spacieux instead of spacieux appartement?

In French, most adjectives (descriptive words) are placed after the noun they describe. This is the opposite of English. So instead of "spacious apartment", you literally say "apartment spacious".

Spacieux ends in an X. Does that mean it is plural?
