Questions & Answers about Nosotros recibimos un mensaje del profesor.
Why does the verb recibimos end in -imos?
Recibimos comes from the regular verb recibir (to receive). In the present tense, when talking about "we" (nosotros), verbs that end in -ir drop the -ir and add -imos.
Is it strictly necessary to include the word nosotros at the beginning?
Where does the word del come from?
The word mensaje ends in "-e". How do I know to use un instead of una?
Unlike nouns ending in "-o" (which are usually masculine) or "-a" (usually feminine), nouns ending in "-e" don't give you a reliable clue about their gender. You just have to memorize whether they are masculine or feminine when you learn them. Mensaje is masculine, so we use the masculine word for "a", which is un.
