You already know reflexive pronominal verbs, where the subject does the action to itself: je me lave (I wash myself). This unit covers two further categories that use the exact same grammatical shape (subject + reflexive pronoun + verb) but mean something quite different, and that English speakers systematically underuse because English doesn't need a matching pronoun to express the same ideas.
The first category is reciprocal pronominal verbs, used with plural or nous/vous subjects to mean "each other" or "one another." Nous nous parlons tous les jours (We talk to each other every day) uses se parler not to mean "we talk to ourselves" but "we talk to one another" — the reflexive pronoun here points the action back and forth between the members of the group, not inward at each individual. Other everyday reciprocals include se voir (to see each other), s'aimer (to love each other), se téléphoner (to call each other), se disputer (to argue with each other), se comprendre (to understand each other). Context and plurality are usually what tell you reciprocal from reflexive: Ils se regardent could mean "they look at themselves" (reflexive, each looking at his own reflection) or "they look at each other" (reciprocal) — French is genuinely ambiguous here just as English "they look at themselves/each other" would be, and when true ambiguity matters, French can add l'un l'autre (each other) for clarity: Ils se regardent l'un l'autre.
The second category is idiomatic pronominal verbs, where the reflexive pronoun is simply a fixed part of the verb's identity and does not mean "self" or "each other" at all — the pronominal form often has a meaning that is different from, or only loosely related to, the non-pronominal verb. Se souvenir de (to remember) is a completely different verb from souvenir (a noun meaning "memory/souvenir" — there is no verb *souvenir without se). Se rendre compte de (to realize) has nothing reflexive about its meaning in English, yet French requires the full pronominal structure: Je me rends compte de mon erreur (I realize my mistake). S'agir de is even more special — it's used only in the impersonal il form and means "to be about/to be a matter of": Il s'agit d'un malentendu (It's a matter of a misunderstanding / It's about a misunderstanding); you can never say je m'agis or elle s'agit, only il s'agit. Other common idiomatic pronominals include se passer (to happen: Qu'est-ce qui se passe? — What's happening?), s'entendre bien avec (to get along well with), se débrouiller (to manage/cope), and se plaindre de (to complain about).
All pronominal verbs, whatever their category, are conjugated with être in the passé composé, and the past participle usually agrees with the reflexive pronoun when it functions as a direct object — Elle s'est levée (she got herself up, participle agrees because se is the direct object) versus Elle s'est rendu compte de son erreur (no agreement, because in se rendre compte, compte is the direct object, not se — se here is an indirect object, so the participle stays invariable). This agreement subtlety is genuinely advanced and trips up even confident learners.

Erreurs fréquentes
- Omitting the reflexive pronoun for idiomatic pronominal verbs, treating them as regular transitive verbs (saying 'je souviens' instead of 'je me souviens', or 'il agit d'un problème' instead of 'il s'agit d'un problème').
- Using s'agir with a subject other than the impersonal il (saying 'je m'agis de' or 'cette histoire s'agit de' instead of restructuring the sentence around 'il s'agit de').
- Missing reciprocal meanings entirely and translating 'each other' with an added phrase when the pronominal verb alone already carries that meaning (over-adding 'l'un l'autre' when it isn't needed for clarity, or under-using pronominal verbs and instead using non-reflexive constructions borrowed from English word order).
- Applying past participle agreement automatically to all pronominal passé composé forms, without checking whether the reflexive pronoun is really the direct object (wrongly writing 'elle s'est rendue compte' instead of the correct invariable 'elle s'est rendu compte').
- Confusing se souvenir de (to remember, verb) with the unrelated noun souvenir, and trying to use 'souvenir' alone as a verb without se.
Pourquoi ça trompe les anglophones
- English expresses reciprocity with a separate phrase ('each other', 'one another') rather than folding it into the verb's pronoun, so learners often either forget the French reflexive pronoun entirely or fail to recognize that se parler already means 'to talk to each other' without needing extra words.
- Idiomatic pronominal verbs like se souvenir, s'agir, and se rendre compte have meanings that don't derive transparently from a 'self' or 'each other' interpretation, so they feel like arbitrary vocabulary rather than an application of a grammar rule, making them easy to forget the reflexive pronoun for.
- The past-participle agreement rule for pronominal verbs depends on identifying whether the reflexive pronoun is a direct or indirect object — a grammatical analysis English never requires learners to perform, since English past participles never change form based on any object.
