In modern usage, a definition is something, typically expressed in words, that attaches a meaning to a word or group of words. The word or group of words that is to be defined is called the definiendum, and the word, group of words, or action that defines it is called the definiens.
A definition is 'the words we use to describe it'. Something can have a meaning without a solid formal definition (love), and likewise something can have a definition but no useful meaning (see InterCal for some good ones). On this page, we assume the thing has some worthwhile meaning.
