Le garcon n'a pas de stylo- does this mean "the boy does not have a pen?"

Yes.

Yes, that is correct. "Le garçon n'a pas de stylo" translates to "The boy does not have a pen" in English.

To break it down:
- "Le garçon" means "the boy" in French.
- "n'a pas" is the negation of the verb "avoir," which means "to have." So "n'a pas" translates to "does not have."
- "de" is a preposition used in negative sentences to indicate the lack or absence of something. In this case, "de stylo" means "a pen" or "any pen."

So, when you put it all together, "Le garçon n'a pas de stylo" translates perfectly to "The boy does not have a pen."
