Puerco

Pronunciation: pu-AIR-co. You want to mush the first two syllables together, almost like "pwAIR".

Plural: los puercos.

Example: El puerco es un animale muy limpio (The pig is a very clean animal).

Note the common root with the English word "pork" (although puerco is not a true cognate, except maybe with porker).

Pu*er"co (?), n. [Sp.]

A hog.

Puerco beds (Geol.), a name given to certain strata belonging to the earliest Eocene. They are developed in Northwestern New Mexico, along the Rio Puerco, and are characterized by their mammalian remains.
