💡 Grammar Points
Always Feminine: 'la boca'
Like most Spanish nouns that end in '-a', 'boca' is a feminine word. So you'll always say 'la boca' (the mouth) or 'una boca' (a mouth).
❌ Common Pitfalls
Using 'my' instead of 'the'
Mistake: "Me duele mi boca."
Correction: Me duele la boca. (My mouth hurts.) When talking about your own body parts, Spanish usually uses words like 'el' or 'la' instead of 'mi' (my) or 'tu' (your). The first part of the sentence ('Me duele...') already makes it clear it's your own mouth.
⭐ Usage Tips
More than just eating
'Boca' is used for talking, shouting, smiling, and breathing. It's the all-purpose word for the entire mouth area and its functions.

Boca can also be used to mean 'opening' or 'mouth' of geographical features, like the mouth of a river.
boca(Noun)

?of a cave, tunnel, bottle

⭐ Usage Tips
A Visual Connection
Think of this meaning as an extension of the first one. Just like a person's mouth is an opening, Spanish uses 'boca' for any opening that looks like one: the 'mouth' of a river where it opens to the sea, the 'mouth' of a cave, or the 'mouth' of a subway station where people go in and out.

Frequently Asked Questions
What's the difference between 'boca' and 'labios'?
'Boca' is the whole mouth—the opening, and everything inside like your teeth and tongue. 'Labios' refers only to the lips on the outside. You use your 'boca' to eat and talk, and your 'labios' to kiss.
Why do people say '¡Cierra la boca!'? Is it rude?
It can be! '¡Cierra la boca!' means 'Shut your mouth!' and is very direct and often rude, just like in English. A more polite way to ask someone to be quiet is simply 'Silencio, por favor' (Silence, please).
