Acheter: Full Verb Reference

Acheter is the verb to buy. Its conjugation is regular -er in stem and endings, with one targeted spelling adjustment: the e in the second-to-last syllable of the stem (ach-*e-ter) becomes è* (e accent grave) whenever the next syllable contains a silent e. This is the -e_er pattern, named after the schwa-then-er template (acheter, lever, peser, mener, semer, geler, peler).

The reason is phonetic: in everyday French, the stem-internal e of acheter is normally a schwa (a brief, unstressed /ə/). But when the next syllable's e falls silent — as it does in the singular forms of the present (j'achète), the 3pl (ils achètent), and throughout the futur and conditionnel — the previous e must take the stress. To mark that stress, French writes è (with grave accent), which is pronounced /ɛ/ (the open e of père, frère). The contrast: nous achetons /aʃ.tɔ̃/ — the stem e is silent, no accent needed; j'achète /ʒaʃɛt/ — the stem e is stressed, grave accent mandatory.

Two sister patterns exist for -e_er verbs: most take the grave accent (acheter → j'achète; peser → je pèse; lever → je lève); a smaller group doubles the consonant instead (appeler → j'appelle; jeter → je jette — see those pages for the doubling pattern). For acheter and its family, the grave accent is the rule.

The verb itself is high-frequency, transitive (acheter du pain), and pivots into a syntactically remarkable construction: acheter quelque chose à quelqu'un, where the à-marked person can be either the buyer (for whom) or the source (from whom) — context decides. This page covers everything.

The simple tenses

These are the tenses formed without an auxiliary. Acheter is regular -er in endings, with the -e_er spelling adjustment kicking in wherever the next syllable's e falls silent.

Présent de l'indicatif

Standard -er endings on the achet- stem, with the grave accent in 1sg, 2sg, 3sg, and 3pl — but not in 1pl or 2pl, where the next-syllable e is pronounced.

The 1sg, 2sg, 3sg, and 3pl all sound identical (/aʃɛt/) — the silent endings -e, -es, -e, -ent don't add a syllable, so the stem-internal e must be stressed and is marked with the grave accent. In nous achetons and vous achetez, the e of the ending -ons / -ez takes the stress, so the stem-internal e falls silent (becoming a schwa or dropping entirely in fast speech). No accent — the e is just a buffer letter.

Imparfait

The imparfait is built on the 1pl present stem achet- (the form without the grave accent). All six imparfait forms therefore lack the accent — the e of the imparfait endings (-ais, -ait, -aient, -ions, -iez) is always pronounced, which keeps the stem e silent.

This is one of the cleaner spots in acheter's paradigm: the imparfait is fully accent-free across all six persons. Pronunciation: /aʃ.tɛ/ in all forms with silent endings.

Passé simple (literary)

Standard 1st-conjugation passé simple endings -ai, -as, -a, -âmes, -âtes, -èrent. Built on the achet- stem — no grave accent at any person, because all endings start with a vowel that gets pronounced.

Futur simple

This is the most distinctive part of acheter's paradigm. The futur stem is achèter- — built from the infinitive but with the grave accent throughout all six persons. Why? Because the e of the futur ending (-erai, -eras, -era, -erons, -erez, -eront) is silent in pronunciation. The actual phonetic shape is /aʃɛt.ʁe/, /aʃɛt.ʁa/, etc. — the stem e must be stressed, hence è.

This contrasts sharply with the imparfait, where no person carries the accent. In the futur, every person carries the accent. The reason: the e immediately after the stem (the e of -er- in the infinitive) is silent in spoken French, so the previous e must be stressed.

Conditionnel présent

Same logic as the futur — same achèter- stem with grave accent throughout, plus imparfait endings. Every person carries the accent.

Subjonctif présent

Standard subjunctive endings on the present-tense stems. Same split as the present indicative: grave accent in 1sg, 2sg, 3sg, 3pl (silent endings); no accent in 1pl, 2pl (pronounced i-endings).

The 1pl achetions and 2pl achetiez are spelled identically to the imparfait — the absence of the accent is the giveaway that 1pl/2pl are unstressed.

Impératif

Three forms. The tu imperative drops the -s — achète, not achètes (still with grave accent, because the silent ending preserves the stress on the stem). The 1pl and 2pl forms come from the present indicative, both without the accent.

Participles and gérondif

• Participe passé: acheté (regular -é; no accent on stem because the é of the ending is pronounced and stressed)
• Participe présent: achetant (no accent — the -ant ending is pronounced)
• Gérondif: en achetant

The participle acheté shows past-participle agreement when used with avoir and a preceding direct object. Les chaussures que j'ai achetées hier — feminine plural agreement achetées because the preceding direct object les chaussures is feminine plural.

The compound tenses

Acheter uses avoir as its auxiliary in all compound tenses. The participle acheté carries no grave accent in the stem (only the regular é of the ending).

Passé composé

avoir (présent) + acheté

Plus-que-parfait

avoir (imparfait) + acheté

Futur antérieur

avoir (futur) + acheté

Conditionnel passé

avoir (conditionnel) + acheté

Subjonctif passé

avoir (subjonctif) + acheté

The major uses

1. Acheter + direct object — to buy (something)

The default transitive use. The thing bought is a direct object, no preposition.

The partitive article du, de la, des is the default for non-count items: acheter du pain, acheter de la farine, acheter des œufs. After negation, du / de la / des contracts to de: je n'achète pas de viande (I don't buy meat).

2. Acheter quelque chose à quelqu'un — buy from / buy for

This is the syntactically fascinating use. The construction acheter qqch à qqn can mean either:

• Buy something FROM someone (the à-marked person is the seller)
• Buy something FOR someone (the à-marked person is the recipient)

Context decides. Same syntactic frame, two opposite roles.

The clue is real-world plausibility: a brocanteur sells things, so à un brocanteur must mean from; a mother is a recipient, so à ma mère must mean for. With pronouns, the same ambiguity exists: je lui ai acheté un livre can mean I bought a book from him OR I bought a book for him — context decides.

If you want to be unambiguous, French offers explicit alternatives:

• pour
  • person — clearly for: j'ai acheté un livre pour ma sœur (no ambiguity)
• chez
  • person/place — clearly at, from: j'ai acheté ce livre chez le libraire du coin (no ambiguity)

3. S'acheter — to buy oneself / to buy each other

The reflexive s'acheter has two readings:

• Self-benefit: to buy oneself something (using the indirect-object reflexive: je m'achète un café — I'm buying myself a coffee).
• Reciprocal: they buy each other (limited use — usually s'offrir is more idiomatic for reciprocal gifts).

In the second example, note that the participle does not agree with the reflexive s' — because s' is functioning as an indirect object (to herself), not a direct object. The direct object is un sac, which follows the verb. (See past-participle agreement rules for reflexive verbs for the full logic.)

4. Figurative acheter — to bribe, to win over

Acheter extends figuratively to bribery or buying loyalty / silence. This is a common journalistic and colloquial use.

In this figurative sense, acheter quelqu'un = to bribe someone. Be careful: this is not the same as acheter quelque chose à quelqu'un, which is the regular transactional use.

High-frequency acheter idioms

• acheter pour une bouchée de pain — to buy for a song (literally: for a mouthful of bread)
• acheter à crédit — to buy on credit
• acheter en gros / en détail — to buy wholesale / retail
• acheter d'occasion — to buy secondhand
• acheter neuf — to buy new
• acheter sur un coup de tête — to buy on impulse
• acheter chat en poche — to buy a pig in a poke (literally: to buy cat in a bag — without inspecting)
• je te l'achète (colloquial) — I'll take that explanation / I buy it
• acheter la paix — to buy peace (figurative — to give in to avoid conflict)

The -e_er family (grave-accent type)

Every -e_er verb in this group follows the same grave-accent rule. Here's the high-frequency core:

The pattern is identical: grave accent in 1sg/2sg/3sg/3pl present, throughout futur and conditionnel; no accent in 1pl/2pl present and throughout the imparfait. If you can conjugate acheter, you can conjugate every verb in this family.

Acheter vs appeler / jeter — the spelling-rule split

Two spelling traditions exist for verbs whose stem ends in -eler or -eter:

• Doubling pattern (appeler → j'appelle, jeter → je jette) — the consonant doubles before silent endings. See the appeler and jeter pages.
• Grave-accent pattern (acheter → j'achète, peler → je pèle) — the e takes a grave accent.

For -eler and -eter verbs, you must memorize which pattern each verb uses. Acheter is the most famous -eter verb that takes the grave-accent pattern, while most other -eter verbs (including jeter) take the doubling pattern. The 1990 spelling reform tried to standardize all of them on the grave-accent pattern, but in practice the traditional split is still dominant in writing.

For -e_er verbs that aren't -eler or -eter (like lever, peser, mener), there's no split — they all take the grave accent.

Comparison with English

Three friction points:

1. The grave accent is not optional. English has no diacritics, and learners often skip the accent in writing. J'achete without the grave is technically a spelling error in French — the è is a real letter, distinct from e, and forgetting it is a stigmatized mistake. Even worse: the futur j'acheterai without the accent is doubly wrong (the accent should appear on the stem in all six futur forms).

2. The à dual role. English clearly distinguishes buy from and buy for. French collapses both into acheter qqch à qqn and lets context disambiguate. This routinely confuses learners — and confuses native speakers' intuitions when they translate. Use pour (for the recipient) or chez (for the seller) when you want to be unambiguous.

3. No present continuous. English distinguishes I buy bread there (habit) from I'm buying bread (right now). French doesn't — j'achète du pain means both. For emphatic ongoing aspect, French falls back on je suis en train d'acheter du pain, but it's heavier and rarely needed.

Common Mistakes

Mistake 1: Forgetting the grave accent in singular forms.

Mistake 2: Adding grave accent to 1pl/2pl present.

Mistake 3: Forgetting the accent throughout the futur.

Mistake 4: Misreading acheter qqch à qqn as always meaning "buy from."

Mistake 5: Using English for literally with acheter.

Key takeaways

Acheter is a regular -er verb meaning to buy. It uses avoir in all compound tenses (j'ai acheté). The conjugation contains exactly one quirk: the -e_er spelling rule, which marks the stem-internal e with a grave accent (è) before any silent ending. This affects 1sg/2sg/3sg/3pl present (j'achète, tu achètes, il achète, ils achètent), the entire futur (j'achèterai, tu achèteras, il achètera, nous achèterons, vous achèterez, ils achèteront), the entire conditionnel (j'achèterais, etc.), and the same singular + 3pl in the subjunctive. The 1pl/2pl present forms (nous achetons, vous achetez), the entire imparfait (j'achetais, etc.), and the participle (acheté) carry no accent — their endings are pronounced, so the stem e falls silent and stays unmarked.

The signature construction is acheter quelque chose à quelqu'un, where the à-marked person can be either the seller (source — acheter à un brocanteur = buy from an antique dealer) or the recipient (beneficiary — acheter un cadeau à ma mère = buy a present for my mother). Context disambiguates; for clarity, French offers explicit alternatives — pour marks the recipient unambiguously, and chez marks the seller / location of purchase.

The entire -e_er family — lever, peser, mener, semer, geler, peler, amener, emmener, promener, enlever, élever, achever — follows the same grave-accent rule. Master acheter and you have the template for all of them. (Note that some -eler and -eter verbs — like appeler and jeter — follow a different pattern: doubling the consonant. See those pages.)
