Questions & Answers about Marco deve lavare la macchina.
Why is the second verb lavare ending in '-are' instead of matching Marco?
Because it follows the modal verb deve (must / has to). When you use a modal verb, the verb that comes right after it stays in its full infinitive (dictionary) form. So we use lavare (to wash) rather than conjugating it again.
Does deve translate to 'must' or 'has to'?
Does macchina literally mean 'machine'?
