The pronouns all and everyone (tous, toutes)

The words tous and toutes can stand alone as pronouns meaning "everyone" or "all of them".

Use tous for a masculine or mixed group, and toutes for a purely feminine group.

Pronouncing the "s" in "tous"

When tous is used as a pronoun, you must pronounce the final "s" (rhyming with "moose"). This is different from the adjective tous (as in tous les jours), where the "s" is silent.

Hello everyone, our colleagues are all here today.
Bonjour à tous, nos collègues sont tous ici aujourd'hui.
He gathered the members, and all of them accepted.
Il a rassemblé les membres, et tous ont accepté.

The feminine "toutes"

For feminine groups, use toutes. The "t" is pronounced, but the "s" is silent.

I looked at the photos, I saw all of them (f).
J'ai regardé les photos, je les ai toutes vues.
She convened the directors (f), but they did not all come.
Elle a convoqué les directrices, mais elles ne sont pas toutes venues.

Reinforcing a pronoun

You can place tous or toutes after a verb to reinforce an object pronoun (like les, nous, or vous).

This decision concerns us all, it is essential to speak about it.
Cette décision nous concerne tous, il est indispensable d'en parler.

You can use both pronouns together in a fixed phrase to explicitly include both men and women:

I answered everyone (m) and everyone (f).
J'ai répondu à tous et à toutes.

La totalité

To express "all of" or "the whole" in a formal setting, use the noun la totalité (the entirety), usually followed by de (or des).

It is essential to read the entirety of the documents.
Il est indispensable de lire la totalité des documents.
The director (f) gathered the entirety of the files on her desk.
La directrice a rassemblé la totalité des dossiers sur son bureau.
