Most cognates have a similar meaning, but in some cases the meaning has changed
in one language or another. For example, in English the word "arena," usually refers to a
sports facility, and in Spanish arena, means "sand." They both come from the Latin harena,
meaning "sand", and also refer to the area of a Roman amphitheater that was covered with
sand. Spanish retained the meaning of "sand" (and the word can sometimes refer to a sports
arena). In English the meaning was expanded to include places that can be compared to
Roman amphitheater.
