Asseoir has several meanings: "to seat someone," "to set down," "to help or make someone sit up or down," "to help someone stand his ground" (in an argument), "to base," "to establish." It is an irregular -ir verb and all irregular verbs ending in -seoir are conjugated the same way; they take avoir as their auxiliary verb. Even more common is the pronominal s'asseoir, which means "to sit down" or "take a seat." In this case, it requires être as the auxiliary verb. S'asseoir is conjugated the same as asseoir.

Asseoir is one of those words that in the 1990 French language reform changed spellings to better reflect pronunciation. Asseoir became assoir, paier became payer, oignon became ognon, and so on. The former spellings were called old; the new spellings were called modernized. The problem is that the French haven't adopted the new changes wholeheartedly because they sound bizarre and, in some cases, archaic.

Two Complete Sets of Conjugations

This left asseoir with two complete sets of conjugations: the old and the modernized. But the first and second person plural (nous assoyons and vous assoyez in the present tense) of the modernized form seem so strange that many French speakers in France will do anything to avoid using them.

The result is a hybrid conjugation that sounds better to the French ear: the old asseyez-vous and assied-toi for commands, and for statements and questions, a combination of the old and modern spellings that goes like this: je assois, tu assois, on assoit, ils assoient, but nous asseyons, vous asseyez. These forms are also used for the pronominal s'asseoir. 

Anything to Avoid 'Nous Assoyons' and 'Vous Assoyez'

Here's an example of a speaker automatically switching from one form to the other: Je m'assois sur la chaise. Si vous vous asseyez sur le canapé, ne mettez pas vos pieds dessus! ("If you sit on the sofa, don't put your feet on it.")

The tables at the bottom of the page show both forms. Strictly speaking, both are correct conjugations of asseoir. Most French speakers will use either one or both ways, and the preference is often driven by regional differences. For instance, Parisians will use a hybrid conjugation as we've described above, while the Québecois prefer to stick with the modern form. By and large, though, the modern form is less frequently used than the old form.

Simple Conjugations of the REGULAR '-ir-' VERB 'ASSOIR'

The post-1990, modernized form, assoir, may be typical of official texts, but it is still the less common conjugation. The first, second, and third person singular, and the third person plural of assoir are very common, probably because of the similarity to the infinitive. But the first and second person plural of the modern form are not.
