French Interrogative Adjectives: Quel, Quels, Quelle, Quelles

Introduction

In Question Formation you saw ‘quel/quelle’ in a single row of a table — here’s the full picture. Quel is French’s “which/what”, but it isn’t one word — it’s a set of four forms that agree with the gender and number of the noun that follows, exactly like demonstrative adjectives (ce/cette/ces). This lesson covers all four forms, the two structures quel appears in, and the most common mix-up: quel vs que.

The Four Forms — Quel’s Agreement

Note: all four forms are pronounced identically (/kɛl/) — the difference is purely written. In speech your ear can’t tell them apart; only the noun that follows tells you which one to write, which is exactly why agreement matters most in writing (TEF/TCF Expression Écrite).

Two Structures — Where Quel Sits

1. Quel + être + noun

When the question asks for the identity of a noun, quel leads the sentence, then être, then the noun — the noun doesn’t disappear, it just sits on the other side of être:

• “Quel est votre sport préféré?” (What is your favourite sport? — sport = m.s.)
• “Quelle est votre adresse?” (What is your address? — adresse = f.s.)
• “Quels sont tes films préférés?” (What are your favourite films? — films = m.pl.)

Golden rule: agreement is always with the noun on the other side of être, even though être sits in between. In “Quel est ton nom?”, ‘nom’ is masculine, so ‘quel’ — être itself has no gender.

2. Quel + noun (directly)

When quel comes straight before the noun, the question is built with inversion or ‘est-ce que’ — the same structures from Question Formation:

• “Quelles couleurs aimez-vous?” (Which colours do you like? — inversion)
• “Quels sont les pantalons de Marc?” (Which pants are Marc’s?)
• “À quelle heure allez-vous au bureau?” (What time do you go to the office? — preposition + quelle, heure = f.s.)
• “Dans quel pays es-tu né?” (In which country were you born? — pays = m.s.)

Preposition + quel: when à, dans, avec, pour, etc. come first, they lead the question — quel still agrees with the noun that follows it, not with the preposition.

Examples

Quel vs Que — Two Different Words

Both translate as “what”, but they’re not interchangeable — they ask about different things:

The test: look at what follows the question word. If it’s a specific noun (livre, sport, heure…), use quel and agree it with that noun. If it’s a verb directly, use que:

• “Que faites-vous?” (What are you doing? — about the verb ‘faites’)
• “Que regardez-vous?” (What are you watching?)
• “Qu’est-ce que tu manges?” (What are you eating? — more common in speech)

The full ‘que’/‘qu’est-ce que’ explanation lives in Question Formation — this lesson is just here to remind you they’re two separate words, not two spellings of the same one.

Common Mistakes

Practise It

Interrogative Adjectives drill: fill in the correct form (quel/quels/quelle/ quelles) in each sentence. Every answer shows the full sentence and why.

Next Steps

• Question Formation — est-ce que, inversion, and the other interrogative words.
• Demonstrative and Possessive Adjectives drill — the same agreement pattern, different meaning.
• Adjective Agreement Guide — agreement for adjectives in general.

Practice: write 5 questions a day starting with ‘quel’ — first with the être structure, then directly with a noun. Say the noun’s gender/number out loud each time, then pick the right form.

To ask “which one?” without a noun, see The Interrogative Pronoun lequel.
