自反动词过去时：我洗了澡 (Passé Composé)

1. 1Reflexive Pronoun as Direct Object: If no other direct object follows the verb, the reflexive pronoun itself functions as the direct object. In such cases, the past participle agrees with this preceding direct object (which is, by definition, the subject).

• Elle s'est lavée hier. (She washed herself yesterday.) – Here, se (herself) is the direct object of lavée. Since it precedes the verb and is direct, lavée agrees with Elle (feminine singular).
• Nous nous sommes amusés à la fête. (We had fun at the party.) – nous (ourselves) is the direct object of amusés, so amusés agrees with Nous (plural).

1. 1Reflexive Pronoun as Indirect Object: If the verb is followed by an explicit direct object (a noun phrase that directly receives the action), then the reflexive pronoun (se, me, etc.) functions as an indirect object, meaning to oneself or for oneself. French past participle agreement rules state that agreement occurs only with a *preceding direct object*. Since the reflexive pronoun is now indirect, and the actual direct object *follows* the verb, no agreement is made with either the subject or the direct object.

• Elle s'est lavé les mains. (She washed her hands.) – les mains (her hands) is the direct object. se means to herself (indirect object for laver à soi). Because the direct object les mains *follows* lavé, the participle remains in its masculine singular form (lavé).
• Ils se sont cassé la jambe. (They broke their leg.) – la jambe is the direct object. se means to themselves (indirect object for casser à soi). cassé remains masculine singular.

1. 1Reflexive Verbs vs. Non-Reflexive (Transitive) Verbs:

• Non-Reflexive: The subject performs an action on an *external* direct object. The auxiliary verb is typically avoir. Agreement of the past participle with the direct object occurs only if the direct object precedes avoir.
• J'ai lavé la voiture. (I washed the car.) – Action on la voiture.
• Reflexive: The subject performs an action *on itself*. The auxiliary verb is always être. Past participle agreement follows the reflexive rules (agree with preceding direct object, often the reflexive pronoun itself, but not if another direct object follows).
• Je me suis lavé(e). (I washed myself.) – Action on me (myself).

1. 1Reflexive Verbs vs. The Passive Voice: Both structures involve être + past participle, but their meanings and grammatical roles are distinct.

• Passive Voice: The subject *receives* an action, often from an unspecified or implied agent (or an agent introduced by par). It describes a state or a result of an action.
• La porte a été ouverte par quelqu'un. (The door was opened by someone.)
• Je suis perdu en ville. (I am lost in the city.) – This describes a state of being lost.
• Reflexive: The subject *actively performs* an action upon itself. It describes the subject as both the agent and the recipient of the action.
• Je me suis perdu(e) dans mes pensées. (I lost myself in my thoughts.) – This implies the action se perdre (to lose oneself), a self-directed action.

1. 1Reflexive Verbs vs. Intransitive être Verbs (e.g., DR MRS VANDERTRAMP): French has a specific group of non-reflexive verbs (often movement or state-change verbs like aller, venir, partir, naître, mourir) that also use être in compound tenses. Both groups agree the past participle with the subject.

• Intransitive être verbs: Describe movement, arrival, departure, or a change of state where the action is not self-directed but happens to the subject.
• Il est allé au cinéma. (He went to the cinema.) – aller is a verb of movement.
• Elle est née en 1990. (She was born in 1990.) – naître describes a state change.
• Reflexive Verbs: Are always marked by the reflexive pronoun (se, me, te, etc.). This pronoun is the unmistakable indicator that the action is self-directed or reciprocal. The core difference is the *presence of the reflexive pronoun*.
• Il s'est promené dans le parc. (He walked himself in the park / He went for a walk.) – se promener is reflexive.

Yes, absolutely. It is a defining characteristic of reflexive verbs in all compound tenses that they take être as their auxiliary, never avoir.

A verb is reflexive if its infinitive form includes the reflexive pronoun se (e.g., se coucher, s'appeler). This se indicates that the action is performed by the subject upon itself. Be aware that many verbs can be used both reflexively and non-reflexively, often with different meanings (e.g., doucher (to shower someone/something) vs. se doucher (to shower oneself)).

The reflexive pronouns me, te, se contract to m', t', s' when they precede a verb form that begins with a vowel or a silent h. Since the être auxiliary forms es and est begin with a vowel, contractions are very common: Tu t'es levé(e), Il s'est habillé. The pronouns nous and vous do not contract.

No. The past participle agrees in gender and number with the subject *only if* the reflexive pronoun functions as a direct object that precedes the auxiliary verb. This occurs when there is no other direct object following the verb (e.g., Elle s'est lavée → se is the direct object). However, if a direct object *follows* the verb (e.g., Elle s'est lavé les mains), then the reflexive pronoun (se) acts as an indirect object (to herself), and the past participle remains in its masculine singular form, showing no agreement with the subject.

Yes. For a specific group of reciprocal verbs, the action is inherently directed *to* or *for* someone/something, making the reflexive pronoun (se, nous, vous) always an indirect object. Therefore, their past participles never agree. Common examples include se parler, se téléphoner, se sourire, s'écrire, se nuire, se plaire, se déplaire, se ressembler, se succéder. For example, Ils se sont parlé longtemps. (se is indirect object, meaning 'to each other').

The negation structure (ne...pas, ne...plus, ne...jamais, etc.) surrounds the reflexive pronoun and the auxiliary verb être. For example, Je ne me suis pas amusé. (I didn't have fun.) or Elle ne s'est jamais sentie seule. (She never felt alone.)

Yes. Although on is grammatically third-person singular and takes est as its auxiliary, in informal French, it often replaces nous (we) and refers to a plural subject. In such cases, it is common and often expected to see the past participle agree in number (and sometimes gender) with the implied plural subject (e.g., On s'est vus hier. if referring to a group of men, or On s'est vues if referring to a group of women).

Je suis perdu (passive voice) means I am lost (describing a state). Je me suis perdu (reflexive) means I got lost (describing the action of losing oneself). The reflexive form emphasizes the action causing the state.
