mais vs mes vs met(s)

Summary

mais = "but" (conjunction); mes = plural possessive "my" (mes amis, singular mon/ma); met/mets = the verb mettre in the present (il met, tu mets); un mets = "a dish" (rare noun). All are pronounced /mɛ/. Tests: mais can be replaced by pourtant ("however"); mes can be replaced by tes or ses; met(s) can be replaced by mettait (imparfait of mettre).

Explanation

Mais, mes, met, and mets are four written forms that all collapse to the same sound, /mɛ/, in spoken French — a classic source of spelling mistakes for learners transcribing what they hear. Despite the identical pronunciation, each form belongs to a distinct grammatical category: mais is a conjunction, mes is a possessive determiner, and met/mets are forms of the verb mettre ("to put"), with mets doubling as a rare noun meaning "a dish" (as in food).

Mais introduces a contrast or opposition, exactly like English "but": il est petit mais fort ("he is small but strong"), j'aimerais venir, mais je suis occupé ("I'd like to come, but I'm busy"). It is invariable and never agrees with anything. A reliable substitution test is to swap it for pourtant ("however/yet") or cependant — if the sentence still makes sense, the word is mais.

Mes is the plural possessive determiner meaning "my," used before any plural noun regardless of gender: mes amis ("my friends"), mes clés ("my keys"). It is the plural counterpart of mon (masculine singular) and ma (feminine singular). The substitution test here is to replace mes with another plural possessive such as tes ("your") or ses ("his/her"): mes amis → tes amis works, confirming a possessive determiner.

Met and mets are conjugated forms of the irregular verb mettre. Met is used for the third-person singular (il met la table, "he sets the table"); mets is used for both the first- and second-person singular (je mets mon manteau, "I put on my coat"; tu mets la radio, "you turn on the radio"). Because they are verb forms, the test is to replace them with mettait, the imparfait of mettre: il met la table → il mettait la table confirms met; tu mets ton manteau → tu mettais ton manteau confirms mets.

A separate, much rarer noun also spelled mets exists: un mets means "a dish" in the culinary sense, as in un mets délicat ("a delicate dish") or un mets régional. It is always preceded by an article (un, le, ce…) rather than a subject pronoun, which distinguishes it instantly from the verb form tu mets / je mets. A fourth, related form worth noting is m'est, the contraction of me + est (from être): il m'est arrivé une chose étrange ("a strange thing happened to me") — here est is the verb être, not mettre, attached to the pronoun me.

In short: mais is the conjunction "but" (test: pourtant); mes is the plural possessive "my" (test: tes/ses); met/mets are mettre conjugated (test: mettait); and un mets is the occasional noun "a dish," always with an article. Reading the surrounding words — is there a noun after it, a subject pronoun before it, or a contrast being drawn — settles every case.

Examples

Il est petit mais très fort. — He is small but very strong. (mais: conjunction of contrast, replaceable by pourtant.)

Mes amis arrivent avec mes clés. — My friends are arriving with my keys. (mes: plural possessive, replaceable by tes/ses.)

Il met la table pendant que je mets mon manteau. — He sets the table while I put on my coat. (met (il) and mets (je): forms of mettre, replaceable by mettait/mettais.)

Ce restaurant sert un mets régional délicieux. — This restaurant serves a delicious regional dish. (un mets: rare noun "a dish," always preceded by an article.)

Il m'est arrivé une chose étrange, mais je vais bien. — Something strange happened to me, but I'm fine. (m'est = me + est (être), contrasted here with the conjunction mais.)
