An ampersand is a shorthand symbol for "and." It looks like this: & .
People often use an ampersand when they want to save space — like when they're writing on Twitter or trying to come up with a cool company logo. The symbol comes from ancient Roman times and can be seen in really old Pompeiian graffiti. The word ampersand is a mix of Latin and English and a condensed version of the phrase "and per se and," which means "(the character) '&' by itself is 'and'."
