Questions & Answers about O cliente não tem de enviar a mensagem agora.
Does não tem de mean "must not" or "doesn't have to"?
Why don't we change the ending of the verb enviar?
Because it is part of the ter de + infinitive structure. When you use a conjugated verb like tem followed by the preposition de to talk about an obligation, the verb that describes the actual action stays in its original dictionary form (the infinitive). Here, that's enviar (to send).
Why is cliente masculine here (o cliente) even though it ends in an 'e'?
Why is the word for "message" feminine (a mensagem)?
