When a French sentence has a plural subject and a pronominal verb, an English reader's first question is often: which reading is this? Ils se regardent — are they looking at themselves (each in his own mirror) or at each other (locked in eye contact)? Elles s'aiment — do they love themselves, or do they love each other? French uses one and the same construction for both meanings, leaning on context and a small toolkit of disambiguators when context isn't enough.
This page covers when ambiguity actually arises, the explicit markers French has for each reading, and the verbs that resolve themselves without help. The basic reciprocal construction is treated more thoroughly on the Reciprocal Pronominals page; here we focus specifically on disambiguation strategies.
The ambiguity, in one sentence
Ils se regardent.
(a) They look at themselves. (b) They look at each other. — Both readings grammatically available.
In isolation, this sentence is genuinely ambiguous. Two men standing back-to-back in a clothing store mirror are looking at themselves; two lovers across a candlelit table are looking at each other. The verb form, the pronoun, the auxiliary — everything is identical. Only the situation tells you which.
In real conversation, ambiguity rarely lasts long because context usually resolves it. Mes parents s'aiment almost certainly means "my parents love each other," not "my parents each love themselves." But when context is thin, or when you want to be unmistakable, French has explicit markers for each reading.
Marker 1: eux-mêmes / elles-mêmes — for the reflexive reading
To force the reflexive reading (each subject acting on himself or herself), add the disjunctive form ending in -mêmes. The form agrees with the subject's gender and number:
| Subject | Reflexive marker |
|---|---|
| masculine plural / mixed | eux-mêmes |
| feminine plural | elles-mêmes |
| nous (any gender) | nous-mêmes |
| vous (any gender) | vous-mêmes |
Ils se regardent eux-mêmes dans le miroir avec satisfaction.
They look at themselves in the mirror with satisfaction. (Each at his own reflection.)
Les jumelles se voient elles-mêmes sur la photo, elles ne reconnaissent personne d'autre.
The twins see themselves in the photo — they don't recognize anyone else.
Nous nous critiquons nous-mêmes plus que les autres.
We criticize ourselves more than other people do.
Vous vous accusez vous-mêmes, alors qu'il n'y a aucune preuve.
You're accusing yourselves when there's no evidence.
The -mêmes ending is reserved for plural subjects. For a singular subject, the issue doesn't arise: je me regarde can only be reflexive (you can't look at yourself reciprocally on your own).
Marker 2: l'un l'autre — for the reciprocal reading
To force the reciprocal reading, add the l'un l'autre construction (with all its gender and number variants). The basic form for two people is l'un l'autre; for three or more, les uns les autres. Variants for feminine (l'une l'autre, les unes les autres) and combinations with prepositions are covered in detail on the Reciprocal Pronominals page.
Ils se regardent l'un l'autre depuis le début du dîner.
They've been looking at each other since the start of dinner.
Les enfants se sont consolés l'un l'autre après la mauvaise nouvelle.
The children comforted each other after the bad news.
Les voisines s'aident l'une l'autre quand l'une est malade.
The (female) neighbors help each other when one of them is sick.
Les pays signataires se respectent les uns les autres.
The signatory countries respect one another.
When the verb takes a preposition, the preposition slips inside l'un l'autre: l'un à l'autre, l'un de l'autre, l'un avec l'autre, l'un sans l'autre. This is the most distinctive piece of the reciprocal toolkit.
Ces deux philosophes ont beaucoup appris l'un de l'autre.
These two philosophers learned a lot from each other.
Les jumeaux ne peuvent rien faire l'un sans l'autre.
The twins can't do anything without each other.
Marker 3: mutuellement / réciproquement — adverbial reciprocal markers
For a more compact reciprocal marker, French has two adverbs: mutuellement ("mutually") and réciproquement ("reciprocally"). Both reinforce the reciprocal reading without the gender-and-number bookkeeping that l'un l'autre requires. They sit slightly higher in register than l'un l'autre; l'un l'autre fits any context, while mutuellement and réciproquement lean toward writing or careful speech.
Les deux scientifiques s'admirent mutuellement, malgré leur rivalité historique.
The two scientists mutually admire each other, despite their historical rivalry.
Ils s'aident mutuellement dans tous leurs projets.
They help each other in all their projects.
Les deux théories se complètent réciproquement.
The two theories complement each other reciprocally.
The fixed expression et réciproquement ("and vice versa") is a useful bonus.
Elle l'apprécie, et réciproquement.
She likes him, and vice versa.
Marker 4: entre eux / entre elles — "among themselves"
The phrase entre eux (or entre elles) means "among themselves" or "between them" and adds a reciprocal flavor with a slightly different nuance: it often carries a sense of exclusion of others — they're doing this together, separately from outsiders.
Les enfants discutent entre eux dans la cour de récréation.
The children are talking among themselves in the playground.
Les frères et sœurs se chamaillent entre eux comme tous les enfants.
The siblings squabble among themselves like all children.
Les associés ont décidé cela entre eux, sans consulter le PDG.
The partners decided that among themselves, without consulting the CEO.
Entre eux doesn't replace the reciprocal construction — les enfants discutent alone wouldn't be reciprocal — but it adds an "in-group" sense to a verb that already has a reciprocal pronominal form.
Verbs that resolve themselves
Many pronominal verbs are inherently reciprocal-only with plural subjects, because the reflexive reading is semantically nonsensical or implausible. For these verbs, no disambiguator is needed.
Verbs that are reciprocal-only
| Verb | Why reflexive doesn't work |
|---|---|
| se rencontrer | You can't "meet yourself" in the everyday sense. |
| se marier | You can't marry yourself. |
| s'embrasser | Hugging or kissing yourself isn't the standard reading. |
| se quitter | You don't part from yourself. |
| se séparer | Same — separating from yourself isn't the everyday meaning. |
| se disputer | Arguing with yourself is rare; reciprocal is default. |
| se battre | Same — fighting yourself is figurative; reciprocal is default. |
| se serrer la main | You can't shake your own hand (with someone else). |
Ils se sont rencontrés au mariage de leur ami commun.
They met (each other) at their mutual friend's wedding. (Reciprocal-only — no ambiguity.)
Mes grands-parents se sont mariés en 1962.
My grandparents got married in 1962.
Ils se sont quittés après dix ans de relation.
They split up after ten years together.
Les deux candidats se sont serré la main avant le débat.
The two candidates shook hands before the debate.
Verbs that lean reflexive
A different set leans reflexive when the subject is plural — usually grooming verbs and routine self-care actions:
| Verb | Default reading |
|---|---|
| se laver | Reflexive — they each wash themselves. |
| se brosser les dents | Reflexive — each brushes own teeth. |
| se coiffer | Reflexive — each does own hair. |
| se maquiller | Reflexive — each puts on own makeup. |
| se réveiller | Reflexive — each wakes up. |
| se coucher | Reflexive — each goes to bed. |
Les enfants se sont brossé les dents avant d'aller au lit.
The children brushed their teeth before going to bed. (Each brushed his/her own — reflexive default.)
Mes filles se sont maquillées avant la fête.
My daughters put their makeup on before the party. (Each did her own — reflexive default.)
A reciprocal reading is theoretically available — children brushing each other's teeth, sisters doing each other's makeup — but it would require explicit context or an l'un l'autre marker.
Verbs that genuinely allow both
A third group is genuinely ambiguous and requires context or an explicit marker:
| Verb | Both readings possible |
|---|---|
| se voir | see themselves / see each other |
| se regarder | look at themselves / look at each other |
| s'aimer | love themselves / love each other |
| se féliciter | congratulate themselves / each other |
| se critiquer | criticize themselves / each other |
| se comprendre | understand themselves / each other |
| se soutenir | support themselves / support each other |
| se respecter | respect themselves / respect each other |
| se connaître | know themselves / know each other |
| se trouver (X) | find themselves (X) / find each other (X) |
Ces deux athlètes se respectent l'un l'autre — c'est une rivalité saine.
These two athletes respect each other — it's a healthy rivalry. (Reciprocal forced.)
Ces deux athlètes se respectent eux-mêmes — c'est pour ça qu'ils performent.
These two athletes respect themselves — that's why they perform well. (Reflexive forced.)
Mes parents se sont félicités l'un l'autre quand j'ai eu mon diplôme.
My parents congratulated each other when I got my degree.
Les concurrents se félicitent eux-mêmes d'avoir relevé le défi.
The competitors congratulate themselves on having met the challenge.
For these verbs, when context is thin, learners and writers should add the appropriate marker.
A test you can apply
When you're not sure whether a sentence is reflexive or reciprocal — or whether your reader will get the intended reading — apply this test:
- Is the verb in the reciprocal-only set? (se rencontrer, se marier, s'embrasser, etc.) → Reciprocal. Done.
- Is the verb in the reflexive-default set? (se laver, se brosser, se maquiller) → Reflexive unless context overrides.
- Is the verb in the genuinely ambiguous set? → Add a marker.
- What does the surrounding context suggest? → If still unclear, add a marker.
The decision is rarely difficult once you've internalized which verbs fall into which group.
A note on past participle agreement
Disambiguation also matters for past participle agreement, because reflexive and reciprocal use the same rule but apply it to different objects. See Past Participle Agreement of Pronominal Verbs for the full system.
For most verbs in both readings, the past participle ends up the same. Elles se sont vues could mean "they saw themselves" (reflexive: se = DO) or "they saw each other" (reciprocal: se = DO) — agreement applies in both cases. For verbs taking à quelqu'un, both readings yield no agreement: elles se sont parlé could be "they spoke to themselves" or "they spoke to each other" — parler à makes se an indirect object either way.
So in agreement terms, the reflexive/reciprocal distinction is invisible. The disambiguator (l'un l'autre, eux-mêmes) is purely for meaning, not for grammar.
Ils se sont parlé l'un à l'autre pendant deux heures.
They talked to each other for two hours. (Reciprocal — but no agreement either way, since parler takes à.)
Ils se sont parlé à eux-mêmes en regardant leur reflet.
They talked to themselves looking at their reflection. (Reflexive — same lack of agreement.)
Source-language note: the lexical contrast English makes
English distinguishes the two readings lexically — "themselves" vs. "each other" / "one another." French distinguishes them through optional disambiguators on top of an identical base construction. Three observations follow:
Don't translate "each other" with a separate French word. The reciprocal meaning is built into the pronominal construction. Ils se parlent already means "they talk to each other" without any added phrase.
Don't translate "themselves" with a separate French word in pronominal sentences. The reflexive meaning is also built in. Ils se regardent can mean "they look at themselves" without adding eux-mêmes — context can do the work.
Use the disambiguator only when context fails. Sprinkling l'un l'autre on every reciprocal sentence sounds heavy and artificial. Native speakers reach for it when needed — typically in writing, when introducing the relationship between two parties for the first time, or when the verb is genuinely ambiguous.
A common over-correction by English-speaking learners is to mark eux-mêmes on every plural reflexive sentence, producing French that sounds belt-and-suspenders. Trust the construction. Add the marker when ambiguity is real.
Common Mistakes
Mistake 1: Using eux-mêmes to mean "each other."
❌ Ils se voient eux-mêmes tous les jours.
Wrong: this means 'they see themselves every day' (reflexive). For 'each other' use l'un l'autre or rely on context.
✅ Ils se voient tous les jours.
They see each other every day. (Default reciprocal reading from context — no marker needed.)
Mistake 2: Adding l'un l'autre unnecessarily, even when no ambiguity exists.
❌ Mes parents se sont mariés l'un l'autre en 1968.
Stylistically off: se marier is reciprocal-only. Adding 'l'un l'autre' is redundant.
✅ Mes parents se sont mariés en 1968.
My parents got married in 1968.
Mistake 3: Trying to translate "each other" as a noun phrase.
❌ Ils parlent à chacun autre.
No such construction in French. The reciprocal sense is carried by the pronominal verb form (se parler), not by a noun phrase.
✅ Ils se parlent.
They talk to each other.
Mistake 4: Forgetting gender/number on l'un l'autre.
❌ Les sœurs se soutiennent l'un l'autre dans les moments difficiles.
Wrong: with two feminine subjects, use l'une l'autre. With three or more, les unes les autres.
✅ Les sœurs se soutiennent l'une l'autre dans les moments difficiles.
The sisters support each other in difficult times.
Mistake 5: Putting the preposition outside l'un l'autre.
❌ Ils ont besoin de l'un l'autre.
Wrong: with verbs taking de, the preposition goes inside the construction — l'un de l'autre.
✅ Ils ont besoin l'un de l'autre.
They need each other.
Key takeaways
- A pronominal sentence with a plural subject can be reflexive ("themselves") or reciprocal ("each other"). The same construction does both.
- Use eux-mêmes / elles-mêmes / nous-mêmes / vous-mêmes to force the reflexive reading.
- Use l'un l'autre (with appropriate gender/number agreement) to force the reciprocal reading. Tuck verb prepositions inside: l'un à l'autre, l'un de l'autre, l'un avec l'autre.
- Adverbs mutuellement, réciproquement, and entre eux are useful additional reciprocal markers.
- Many verbs decide for themselves: se rencontrer, se marier, s'embrasser, se quitter are reciprocal-only; grooming verbs (se laver, se brosser, se maquiller) lean reflexive.
- Don't over-mark: native speakers add a disambiguator only when context is genuinely thin. Trust context first, mark explicitly when needed.
- Past participle agreement is the same in both readings — the disambiguator is purely semantic.

- Verbes Pronominaux: OverviewA2 — French pronominal (reflexive) verbs use a pronoun matching the subject — me, te, se, nous, vous, se. They cover four functions: true reflexive, reciprocal, intrinsic, and passive. All pronominal verbs use être in compound tenses.
- Verbes Pronominaux Réciproques: action mutuelleA2 — Reciprocal pronominals express 'each other' or 'one another' — actions that plural subjects do mutually. The same little 'se' that marks reflexive verbs also carries the reciprocal load, with 'l'un l'autre' available when you need to remove ambiguity.
- L'Accord du Participe Passé des Verbes PronominauxB1 — Pronominal verbs use *être* in compound tenses but follow a different agreement rule than other *être* verbs: the past participle agrees with the reflexive pronoun *only when that pronoun is the direct object*. Body-part constructions and verbs taking *à quelqu'un* are the trap.
- Reflexive Pronouns: me, te, se, nous, vous, seA2 — Reflexive pronouns (me, te, se, nous, vous, se) accompany pronominal verbs and refer back to the subject. They sit before the verb in normal sentences, attach with hyphens after affirmative imperatives, and force the auxiliary être in compound tenses.
- Verbes Essentiellement PronominauxA2 — Some French verbs always carry a reflexive pronoun even when there is no reflexive meaning at all — *se souvenir*, *se moquer*, *s'évanouir*, *se taire*. The 'se' is part of the verb's lexical entry. A second category of verbs has both pronominal and non-pronominal forms with completely different meanings.
