To talk about something that has just happened in French, you can use a special structure called the recent past, or 'passé récent'. It's very common in spoken French.

The formula is simple: you take the verb 'venir' in the present tense, add the word 'de', and then follow it with the main verb in its infinitive form. For example, 'Je viens de manger' literally means 'I come from eating', but is used to say 'I have just eaten'.

Let's start with the 'I' form. The present tense of 'venir' for 'je' is 'viens'. So, to say 'I have just done something', you use the phrase 'je viens de' followed by the action. For example, 'Je viens d'arriver' means 'I have just arrived'.

For the informal 'you', the form is 'tu viens de'. It sounds the same as the 'je' form, so the context of the conversation is important. For example, 'Tu viens de téléphoner' means 'You have just called'.
