    Usage notes

    The most recent usages, compose and constitute, whereby the passive form effectively means “the members comprise the team”, are usually informal and often considered incorrect. By classical definition, a team comprises its members, whereas the members compose the team. It is not proper to use comprise in place of compose. With regard to journalistic writing, the Associated Press Stylebook maintains this distinction. These usages are, however, quite common, with the "compose" variation being more common than the "constitute" one.

    According to Webster's Dictionary, the usage dates back to the late 18th century, when it was usually found in technical writing. Webster's indicates that this usage is becoming increasingly common in nontechnical literature, while and state that it is an increasingly frequent and accepted usage.

    The use of "of" with an active use of the verb is unequivocally incorrect (see of: composition), thus "the UK comprises of four countries" and "a round comprising of four games" are incorrect.
