What this table tells you about vieillir

Aux

The past participle is vieilli, and it takes avoir in the passé composé — so it never changes shape, whoever the subject is. No agreement to remember here.

Stem

The futur simple is built on vieillir-, which is just the infinitive — the endings are the whole story, nothing new to learn for this tense.

Sound

In the present, je, tu and il/elle are one sound: vieillis, vieillit — indistinguishable spoken. Only nous, vous and ils/elles carry an audible ending.

Easy win

The imparfait is built on the nous-present stem, so once you know vieillissons you already know vieillissais, vieillissait and vieillissaient. Futur proche keeps vieillir untouched.
