Construire Conjugation French: The Ultimate Master Guide

Mastering construire conjugation in French is a major milestone for any serious language learner. Meaning "to build" or "to construct", construire is a third-group irregular verb ending in -uire.

Because it belongs to the same family as traduire (to translate), conduire (to drive), and détruire (to destroy), mastering this single pattern unlocks dozens of other essential French verbs. This comprehensive guide covers every tense, rule, and nuance you need to know.

1. Present Tense (Présent de l'indicatif)

In the present indicative tense, the stem changes between singular and plural persons. The singular forms end in -s, -s, -t, while the plural forms introduce an "s" pronounced as a soft [z] sound before the standard endings (-ons, -ez, -ent).

Subject Pronoun Conjugation Pronunciation (Approx.)
:--- :--- :---
Je construis kohn-strwee
Tu construis kohn-strwee
Il / Elle / On construit kohn-strwee
Nous construisons kohn-strwee-zohn
Vous construisez kohn-strwee-zay
Ils / Elles construisent kohn-strweez

Example: Nous construisons un projet ambitieux. (We are building an ambitious project.)

2. Past Tenses: Passé Composé & Imparfait

Passé Composé

Construire takes the auxiliary verb avoir. Its past participle is construit.

  • J'ai construit – I built / have built
  • Tu as construit – You built
  • Il/Elle/On a construit – He/She/One built
  • Nous avons construit – We built
  • Vous avez construit – You (pl./formal) built
  • Ils/Elles ont construit – They built

Agreement alert: The past participle agrees with the direct object only if it precedes the verb (e.g., La tour qu'ils ont construite).

Imparfait (Imperfect)

To form the imperfect tense, drop the -ons from the nous form in the present (construisons -> stem: construis-) and add standard imperfect endings:

  • Je construisais
  • Tu construisais
  • Il/Elle construisait
  • Nous construisions
  • Vous construisiez
  • Ils/Elles construisaient

    • 3. Future & Conditional Tenses

Both the future and conditional stems are formed by removing the final "e" from the infinitive, leaving construir-.

Futur Simple

  • Je construirai
  • Tu construiras
  • Il/Elle construira
  • Nous construirons
  • Vous construirez
  • Ils/Elles construiront

    • Conditionnel Présent

  • Je construirais
  • Tu construirais
  • Il/Elle construirait
  • Nous construirions
  • Vous construiriez
  • Ils/Elles construiraient

Example: Si j'avais du temps, je construirais une cabane. (If I had time, I would build a cabin.)

4. Subjunctive & Imperative

Subjonctif Présent

Used after expressions of necessity, emotion, or desire (il faut que...):

  • Que je construise
  • Que tu construises
  • Qu'il/elle construise
  • Que nous construisions
  • Que vous construisiez
  • Qu'ils/elles construisent

    • Impératif (Commands)

  • Construis ! (Build! - informal)
  • Construisons ! (Let's build!)
  • Construisez ! (Build! - formal/plural)

    • 5. Pro Tips for Remembering "Construire"

1. The -uire Family Rule: Whenever you conjugate verbs like reconstruire, instruire, produire, or séduire, apply the exact same endings.

2. Watch the Silent Endings: In je construis, tu construis, and il construit, the final consonants (-s and -t) are silent. They all sound like "kohn-strwee".

3. Idiomatic Usage: Construire is not just for buildings. French speakers regularly use it abstractly: construire une relation durable (to build a lasting relationship) or construire un argument (to build an argument).
