    Sayings and Expressions

    Learning another language can be great fun when you start getting the hang of conversational sayings and expressions. You get to discover a whole cultural framework that is different and exciting. Although they tend to vary from region to region and country to country, there are many sayings that transcend borders and boundaries, and become quite widely used and accepted for their versatility and communicative effect. One of these is the expression “Por su boca muere el pez."

    Literally, it means...

    Literally, it translates to “the fish dies by its mouth," where the fish represents the person being talked about or even addressed directly, and “dying by the mouth" stands for being caught, hooked, or snagged. It refers to someone saying too much, or saying more than is good for them. That is, "el pez por su boca muere" means someone has given himself (or herself) away by saying something they did not mean for others to know.

    The saying, “El pez por su boca muere," is best understood if you put it into context.

    When to say it

    Say a friend stands you up. When you ask what happened she gives you a lame excuse. As she stretches out her explanation more than necessary, you catch her in a lie, and that is when you say, “El pez por su boca muere." Meaning, you just gave yourself away! I caught you! Liar, liar pants on fire!

In Latin American culture, telling the truth is valued, and equally so, reading into what someone is saying to discover or disclose the truth behind the words. There are layers and layers of meaning in normal interactions in Spanish, and you can learn to read into them by learning proverbs, sayings and common expressions.
