Le Présent: Conduire et la famille -uire

The verbs ending in -uire are one of the most rewarding families to learn in French because the work-to-payoff ratio is excellent. Memorize the conjugation of conduire (to drive) once, and you instantly own the conjugations of traduire (to translate), produire (to produce), construire (to build), introduire (to introduce), séduire (to seduce), détruire (to destroy), instruire (to teach), cuire (to cook), and a handful of others — all of them very common, all conjugating identically.

The pattern is the cleanest of the irregular -re families: the singular forms end in -uis, -uis, -uit, and the plural forms add a -s- between the stem and the ending, giving -uisons, -uisez, -uisent. The past participle ends in -uit (no -s), the imperfect uses the plural stem (je conduisais), and the passé simple is je conduisis. Once the spelling pattern clicks, the whole family is yours.

This page lays out the full present paradigm of conduire, walks through the family of -uire verbs, surveys the most common usage patterns, and previews the past participles in -uit.

The model — conduire (to drive)

The three singular forms conduis, conduis, conduit are pronounced identically — /kɔ̃dɥi/. The -s and -t endings are silent, and the visible difference between them is purely orthographic. The three plural forms add the -s- of the conduis- stem, which becomes audible as /z/ before a vowel (between two voiced sounds): conduisons /kɔ̃dɥizɔ̃/, conduisez /kɔ̃dɥize/, conduisent /kɔ̃dɥiz/.

The cluster /dɥi/ — the consonant /d/ followed by the semi-vowel /ɥ/ and the vowel /i/ — is itself a small pronunciation challenge. The /ɥ/ is the rounded version of /j/, the same glide that appears in huit, lui, suis, depuis. English speakers tend to substitute /w/ (saying /kɔ̃dwi/) or to flatten it out (/kɔ̃di/). Neither is right; the lips need to round during the /ɥ/.

The family — same template, just memorize once

The -uire family contains roughly a dozen verbs that all conjugate identically with conduire. The differences between them are purely lexical (different prefixes for different meanings); the conjugation engine is the same.

The two exceptions to know — nuire and luire

The cleanness of the -uire family does have two small wrinkles. The verbs nuire (to harm) and luire (to shine, gleam) conjugate identically in the present, but their past participles end in -ui (no -t), not -uit:

• nuire → past participle nui (not nuit; nuit is the noun "night")
• luire → past participle lui

These are the only two members of the family that break the -uit pattern in the past participle. Both are mid-frequency, and nuire is more common — it appears in fixed expressions like nuire à quelqu'un (to harm someone) and cela ne nuit pas (that doesn't hurt).

The full present conjugation of nuire — je nuis, tu nuis, il nuit, nous nuisons, vous nuisez, ils nuisent — and luire — je luis, tu luis, il luit, nous luisons, vous luisez, ils luisent — is otherwise identical to conduire. The only difference shows up in the past participle.

Usage notes — what each verb does in the wild

Most of these verbs are transitive — they take a direct object — and use avoir in compound tenses.

Conduire

The literal meaning is to drive a vehicle. By extension, conduire also means to lead, guide, take in the sense of physically accompanying someone somewhere:

The construction conduire quelqu'un quelque part — to drive/take someone somewhere — is everyday French. The verb covers both the transport sense (driving in a car) and the broader leading sense (showing the way). For purely abstract leading or guiding (leading a project, leading a discussion), French prefers diriger or mener.

Traduire

The standard verb for translation, taking the prepositions de (from) and en or vers (into):

The everyday version uses en: traduire en anglais. The more formal or technical version uses vers: traduire vers l'anglais, common in professional translation contexts. Both are correct; en is more conversational.

Produire, construire, détruire

These are the workhorses of news, business, and engineering vocabulary. Produire covers everything from manufacturing (produire de l'électricité) to creative output (produire un film) to causing an effect (produire un résultat). Construire is literal building; détruire is its destruction.

Séduire

Séduire covers a wider range than English seduce. It includes the romantic sense, but also the everyday sense of to charm, to win over, to appeal to. A film or a restaurant or an idea can séduire you without any romantic implication.

The narrowly romantic English meaning is one slice of the French verb's range. Don't read every séduire as flirtatious — context decides.

Cuire

Cuire is the kitchen verb — to cook (something), to bake, to roast, to boil. It can be transitive (je cuis le poulet — I'm cooking the chicken) or intransitive (le poulet cuit — the chicken is cooking). The past participle cuit is the everyday adjective for "cooked, done":

The fixed expression bien cuit (well done — for steak), à point (medium), saignant (rare), bleu (very rare) is essential restaurant vocabulary.

Past participles — all in -uit

Apart from nui and lui (the only two exceptions noted above), every member of the family forms its past participle by replacing the -re of the infinitive with -t:

The final -t is silent in the masculine singular but reappears in the feminine -ite (conduite, traduite, construite, séduite) and in liaison.

All compound tenses use avoir — these verbs are transitive. The one place to watch out: conduire is a verb of motion in meaning ("to drive somewhere"), and English speakers sometimes assume verbs of motion take être in French. They don't, unless they appear on the closed list of aller, venir, partir, arriver, ... — and conduire is not on that list. Always j'ai conduit, never /je suis conduit/.

The pattern across other tenses

The -uis- stem (the plural-present stem) is the foundation for the imperfect, the present subjunctive, and the present participle. The infinitive stem (-uir-) is the basis for the future and conditional.

• Imperfect: je conduisais, nous conduisions, ils conduisaient (built on conduis-)
• Subjunctive: que je conduise, que nous conduisions (built on conduis-)
• Present participle: conduisant (built on conduis-)
• Future: je conduirai, nous conduirons (built on conduir-)
• Conditional: je conduirais, nous conduirions (built on conduir-)
• Passé simple (literary): je conduisis, il conduisit, ils conduisirent (built on conduis-)

This regularity makes the family a great teaching example: knowing one form of one verb gives you most of the rest.

A note on register

All the verbs in this family are everyday vocabulary. Conduire is A1; traduire, produire, construire, détruire are A2. Introduire, séduire, déduire, instruire are B1 in frequency but otherwise easy. Reconduire in the formal sense ("to renew a contract, to extend a residence permit") is administrative French; the literal sense ("to drive back") is conversational.

None of these verbs are formal-only or archaic. The whole family is workhorse vocabulary across journalism, business, science, and daily speech.

Common Mistakes

Mistake 1: Using être as the auxiliary for conduire.

Mistake 2: Past participle without the -t.

Mistake 3: Adding an -s- to the singular forms.

Mistake 4: Wrong preposition with traduire.

Mistake 5: Pronouncing /w/ instead of /ɥ/.

Mistake 6: Past participle of nuire with a -t.

Key takeaways

The -uire family is the most regular irregular family in French. Once you know conduire, you know traduire, produire, construire, détruire, introduire, séduire, instruire, cuire, and the rest of the family — every one of them following the same template. The pattern is total: same singular forms, same plural -s- insertion, same -uit past participle (with the two minor exceptions nui and lui).

The two pronunciation challenges are the consonant cluster /dɥi/ in the singular (don't reduce the /ɥ/ to /w/) and the audible /z/ that surfaces in the plural before vowel endings (conduisons /kɔ̃dɥizɔ̃/).

Drill conduire once, internalize the template, and a whole productive corner of French verb morphology becomes effortless. This family alone gives you the vocabulary to talk about driving, building, destroying, producing, translating, instructing, and cooking — the verbs that show up in news, family conversations, recipes, and business meetings every day.
