Glad to have you here today! Reflexive verbs in French are verbs which mean an action done to oneself, for example, laver means 'to wash', but se laver means 'to get washed' or literally ‘to wash oneself’.
That's why in the infinitive form the verb has se in front of it and this needs to change as we talk about other people doing the action just as in English – he has a wash/he washes himself or we are having a wash/we wash ourselves.
How to form a sentence using a reflexive verb
Reflexive verbs follow the normal formation patterns and many are regular -er verbs. They just have an extra pronoun. Remember that me, te, se become m', t', s' before a vowel or silent -h:
*s’appeller
je m'appelle
tu t'appelles
il/elle/on s'appelle
nous nous appelons
vous vous appelez
ils/elles s'appellent
