CULTURAL MOMENT 🍅

Here's something worth noticing: Spanish speakers almost never say this with a singular fly. It's always moscas, plural.

This isn't random. Spanish tends to use plural nouns in proverbs and general statements far more than English does. Think about it in English: we'd probably say "a fly won't get in," singular, focused on one bug.

Spanish assumes multiple flies are always trying to get in, which actually fits the logic better, it's not about one specific fly, it's about the general principle that nothing gets in if your mouth stays shut.

The verb "entran" is also worth slowing down on. It's the present tense of "entrar" (to enter), conjugated for "ellas" (they, referring to the flies) "entran," not "entra." This is a small but telling detail: because moscas is plural, the verb has to match.

A lot of learners get tripped up on subject-verb agreement in Spanish because English doesn't always require this level of matching. Spanish does, every time, no exceptions.

Notice too that there's no article before "boca" or "moscas," Spanish doesn't say "la boca cerrada" or "las moscas" here, even though both are grammatically fine in other contexts.
