Sierra is a Spanish word that means 'mountain range' in English. It is the name given to a long series of mountains that are joined together. You might use the word 'sierra' when speaking about a mountain range, like the Sierra Nevada in California or the Sierra Madre in Mexico. It's important to know that 'sierra' is a specific term and is not used to describe a single mountain, but rather a series of mountains connected to each other.
