Avoir l’air and avoir l’air de are common French expressions used to describe how something or someone seems. They link what is seen or felt to an idea or guess. The first is followed by an adjective or noun. The second is followed by a verb in the infinitive.

Literal meaning

Word for word, avoir l’air means “to have the air.” In plain English, this becomes “to look” or “to seem.”

• Il a l’air fatigué. “He looks tired.”
• Il a l’air d’un prof. “He looks like a teacher.”

Here, l’air refers to outward appearance or manner.

Agreement note

With avoir l’air + adjective, you may see both forms:

• Elle a l’air contente.
• Elle a l’air content.

The first agrees with the subject. The second treats the expression as fixed. The second isn’t actually agreeing the adjective with l’air, but rather treating the expression as a fixed masculine singular one. Another example of the second one is “Elles ont l’air content.”

Both are used. Agreement is more common in careful speech.
