faire — weather, causation, and almost everything else

What this is

faire has been sitting quietly in the background of this course since the very first module — you’ve already seen je fais, il fait, nous faisons scattered across earlier examples, glossed simply as “to make / do.” What none of that showed you was the whole verb: how the plural forms actually work, and the handful of jobs faire does that have nothing to do with making or doing anything at all. This concept fills in the paradigm completely, then hands it two of its biggest jobs — talking about weather, and describing a favor or a job you had someone else do for you.

The rule

faire is one of the most irregular verbs in the language, and two of its six forms break their own pattern in different ways.

Two things to flag immediately, because they will trip you up if you try to derive them by ear from spelling rules learned elsewhere:

• faisons is written with ai, which almost everywhere else in French says roughly “eh” (je sais, il fait itself). Here it says “euh” — the word is pronounced closer to feu-zon than feh-zon. It’s the single most irregular sound in the present tense of any common verb.
• faites looks like it should be faisez, following the -ez pattern every other nous/vous pair uses (faisons/faisez would match parlons/parlez). It isn’t. faites is simply memorized.

Beyond the paradigm, faire covers a set of everyday idioms built the same way every time: faire + a definite or partitive article + an activity.

Notice the article changes with the idiom — du sport (partitive, an uncountable activity) but la cuisine, la vaisselle, la queue (definite, a specific named task). There’s no single rule that predicts which article a given faire idiom takes; each one is learned as a fixed chunk, the same way English speakers just know it’s “do the dishes” and not “make the dishes.”

Why it works this way

faire’s irregularity isn’t random noise — it’s the fossilized remains of Latin facere, which has worn down unevenly across thirteen-plus centuries of spoken use. High-frequency verbs erode irregularly precisely because they’re used constantly: a verb spoken a thousand times a day accumulates shortcuts and sound-changes that a rare verb never has the exposure to develop. faisons and faites are two separate, unrelated erosions of the same original stem, which is exactly why they don’t follow each other.

The idiomatic uses follow from faire’s core sense of “to bring about, to produce” stretched metaphorically: you produce a state of cleanliness (le ménage), you produce a meal (la cuisine), you produce physical activity (du sport). English does the same kind of metaphorical stretching with “make” and “do,” just not along the same lines — which is exactly why you can’t translate these idioms word for word.

Edge cases

faisons and faites don’t follow from spelling or from each other

Treat these two forms as vocabulary to memorize outright, not grammar to derive. Every other verb in this course lets you predict the nous/vous forms from the stem; faire is the one place that trick fails completely. If you only remember one thing from this page, make it this: faisons sounds like “feuzon,” and faites is not faisez.

Weather always uses faire, never être

French describes weather with il fait + an adjective — il fait beau (it’s nice out), il fait chaud (it’s hot), il fait froid (it’s cold) — and also with il fait du + a noun for wind and sun: il fait du vent (it’s windy). English speakers reach for être here because English weather statements use “to be” (it IS cold), but il est froid in French doesn’t describe the weather at all — it describes some specific masculine thing, already under discussion, being cold to the touch. Weather has no subject to be anything; French sidesteps that by making the weather something the impersonal il does.

faire + infinitive means causing, not performing

faire réparer ma voiture does not mean “to repair my car” — it means “to have my car repaired,” by someone else. This causative construction puts faire in front of a bare infinitive to say that the subject is causing the action rather than carrying it out personally. Je répare ma voiture (I fix my car myself) and Je fais réparer ma voiture (I have my car fixed) describe two completely different Saturdays, and the only difference on the page is one word: fais.

What English speakers get wrong

The most common mistake is reaching for être in weather sentences, for the reason above — it’s a direct, word-for-word transfer from English “it is” that simply doesn’t map onto how French frames weather at all.

The second is trying to build the idioms compositionally instead of learning them as chunks — guessing “faire les plats” instead of faire la vaisselle, or “faire le sport” instead of faire du sport. There’s no shortcut here; each idiom’s article has to be learned along with the phrase.

The third is assuming faisons and faites will sound the way they’re spelled, because every other -er-shaped verb in the course has trained you to trust the spelling. faire is the one place that trust has to be suspended.

Closing the module: five verbs, five patterns

faire closes out M9’s five-concept tour of the irregular verbs you cannot avoid. Look back at what each concept actually taught: aller/venir share no stem with their own infinitives at all; pouvoir/vouloir/devoir share one boot-shaped stem change across all three; savoir/voir/connaître split the single English verb “to know” into two genuinely different French verbs; prendre/mettre look like regular -re verbs until their plural doubles a consonant; and faire breaks its own pattern twice, in faisons and faites separately. None of these ten verbs is optional — every one of them will show up in the next few sentences you actually try to say in French — and none of them follows the three regular families from M3 and M8. That’s exactly why they earned their own module, grouped by shared shape rather than memorized as an undifferentiated list.
