we use avoir or etre with marcher(v.) ?
how do we conjugate marcher au passe compose? I know it's with avoir, but it shows movement! as far as I know, we use etre with such verbs!
Where I'm from, we're taught the mnemonic "Mrs Van der Tramp" to remember the verbs that take être (OK this is not exhaustive - I'm pretty sure devenir should also be on the list, and also all reflexive verbs). You're right that they mostly have a movement element to them, but that's not a great way of remembering because there are other movement verbs that take avoir. The best you can do is have this list in mind while you're learning, until you've done enough repetitions that it starts to come naturally.
