Do "formal vous" and "plural vous" always have the same conjugation?

Question

In English, the second person subject pronoun is always “you”, but French has two words: tu and vous.

• Tu is the familiar you,
• Vous is the formal you,
• Vous is also the plural you.

Now, in sense of conjugation, will the “formal vous“ and “plural vous” always behave the same?

Answer 1

Yes, the conjugation between the formal and plural you (vous) is always exactly the same.

Now, slightly related to your question, the plural of adjectives is different. For example:

• to a single woman:

  Vous êtes belle.

• to several women:

  Vous êtes belles.
