Quel and quoi both translate to what.

Is there any rule that tells which one should be used?

    Really? I always worked under the assumption that quel translated to which...

    You will notice that Quel is always followed by a noun, whereas Quoi is never.

  • @Rerito Not in the interrogative form: "Quel est ton nom ?"

1. Quoi = what (indirect object)

Don't use quoi in written French without a preposition, as quoi stands for indirect objects -- except in fixed expressions like quoi qu'il en soit (nevertheless).

Quoi only appears in questions as the second word, directly after the preposition. Typical prepositions are de, à, sur, sous, en, pour (in this case, both words are written together in pourquoi). For example: de quoi parles-tu ? (what are you talking about?); à quoi fais-tu allusion? (what are you referring to?)

Quoi is used in the colloquial mainly spoken French as a substitute for que in non-inverted questions: tu fais quoi ? standing for que fais-tu ? (what are you doing?)

2. Quel

Quel exists in two forms: as a pronoun and as an adjective:

Quel as a pronoun = what (direct object)

Quel as a pronoun is variable, depending on the object is refers to, and is often subject of a question: quel est ce film ?; quelle est cette plante ?; quels sont ces pays ?; quelles sont ces couleurs ?

Quel as an adjective = which

Quel as an adjective is variable, depending on the noun following it; Quelle heure est-il ?; Quel film aimes-tu ?; Quels pays as-tu visités ?; Quelles couleurs préfères-tu ?

3. Qu'elle = that she

Don't mix up quelle and qu'elle. Qu'elle stands for que elle which means that she as in l'homme qu'elle aime (litt. the man that she loves)

    "Quoi" is not "misused" in spoken French and "tu fais quoi ?" is not "grammatically incorrect". The fact that formal written French and colloquial spoken French use different structures doesn't mean that the latter is incorrect. From a linguistic point of view, claiming that "tu fais quoi ?" (a structure used by essentially every native French speaker) is incorrect is absurd.

Quelle heure est-il ? -> What time is it?

Quel est celui que tu préfères ? -> Which one do you prefer?

Tu fais quoi ? (fam.) -> What are you doing?

Quel ou quoi peuvent être utilisés dans de nombreux contextes, et avec des déclinaisons :

Lequel ? Que fais-tu ?

Quel est utilisé pour désigner une chose, tandis-que quoi est plus abstrait.

Quel chien préfères-tu ? Quoi de mieux qu'une journée de pêche ?


"Quel" translated to "which" rather than "what".

    C'est un peu plus compliqué que ça.
