        II. Pronominal Verbs (Note: All pronominal verbs take être as auxiliary.)  | 
      
      
        |   | 
          | 
        A. | 
        Verbs that are always, only pronominal (not many *) -- Agreement is made with Subject (i.e. the same rule of agreement as with non-pronominal verbs taking être as auxiliary).  | 
      
      
        |   | 
        4. Elles se sont souvenues.  | 
      
      
        |   | 
        * Some of the verbs that are always, only pronominal: se souvenir, se repentir, s'enfuir, s'abstenir, s'agenouiller, s'écrier, s'efforcer, s'évanouir, se révolter.  | 
      
      
        |   | 
        B.  | 
        Verbs that are pronominal, but that may be used also as non-pronominal verbs (the majority of pronominals) -- No agreement, unless Direct Object precedes the verb, and then, agreement with preceding Direct Object. This rule is the same, then, as with non-pronominal verbs taking avoir as auxiliary. Note: The preceding Direct Object will occur as a Reflexive Pronoun for pronominal verbs.  | 
      
      
        |   | 
        5. Elles se sont lavées. (se is the preceding D.O.; agreement made with D.O.  | 
      
      
        |   | 
        6. Elles se sont lavé les mains. (D.O. = les mains & D.O. does not precede verb -- No agreement. Se functions as an Indirect Object, indicating whose hands.  | 
      
      
        |   | 
      
      
        |   | 
        7. Nous nous sommes arrêtés.  | 
      
      
        |   | 
        8. Nous nous sommes parlé. | 
      
      
        |   | 
      
      
        |   | 
        Note that the verbs in the four examples (5.-8.) can be used non-pronominally, and then take avoir as auxiliary:  | 
      
      
        |   | 
        For 5. and 6. : Elles ont lavé la voiture.  | 
      
      
        |   | 
        For 7. : Il avait arrêté le voleur.  | 
      
      
        |   | 
        For 8. : Tu auras parlé au président.  |
