Learn French: Il fait partie de notre équipe.

In French, the standard expression for 'to be part of' or 'to belong to' a group is faire partie de. Translating 'he is part of' word-for-word as il est une partie de sounds unnatural.

Why isn't there an article before partie (like fait une partie)?

Faire partie de is a fixed verbal expression. In this specific phrase, partie doesn't take an article like une. The words group together to form a single continuous idea.

This lesson is about verbs taking de. Why is de used here before a noun (notre équipe) instead of an infinitive?

Many verbs and fixed expressions require de to connect to whatever follows them. Just like essayer de requires de to connect to an action, the phrase faire partie requires de to bridge the gap to the noun group it belongs to.

Quick refresher: why is it notre and not nôtre?

Notre (no accent) is the possessive adjective 'our' and must be followed by a noun, like notre équipe. Le nôtre or la nôtre (with the accent) is the pronoun 'ours', used to replace the noun entirely.
