The word "composition" includes the prefix "com-", which means "with", "together", "in association". The origins of the word go back to the Latin form, "componere", which means "put together". When we talk of the composition of something, we mean the elements that were put together, combined, to form that thing. For instance, if you think of composing music, different sounds and instruments are put together in a harmonious way to form the musical piece that will be enjoyed by those who listen.
