comprise

v.
US //kəmˈpɹaɪz// UK //kəmpɹˈaɪz// com·prise
  1. 1 to consist of (v.)
    B2 Upper Intermediate Academic Formal

    to be made up of several different things or people.

    to be composed of or consist of specific parts or members. In strict formal usage, the whole comprises the parts.

    Example

    The country comprises twenty different states, each with its own local government.

    Example

    The final report comprises five distinct sections, ranging from the initial methodology to the long-term policy recommendations.

    Usage

    The verb is transitive and takes a direct object without the preposition 'of'.

    Teacher's tip

    Learners often confuse 'comprise' with 'compose'. A helpful rule: the whole comprises the parts, but the parts compose the whole.

    Pitfall
    The team is comprised of ten players.
    The team comprises ten players.

    In traditional formal writing, 'comprise' is used in the active voice without 'of'. While 'is comprised of' is common in speech, many writers prefer 'is composed of' or simply 'comprises'.

  2. 2 to make up a whole (v.)
    C1 Advanced General-service

    to be the parts that form a larger group or thing.

    to constitute or make up a whole. This sense is often considered less formal than the 'consist of' sense.

    Example

    Older people comprise a large part of the local population.

    Example

    Minority groups comprise nearly forty percent of the student body, reflecting the diverse nature of the surrounding urban community.

    Usage

    In this sense, the parts are the subject and the whole is the object.

    Teacher's tip

    While common in modern English, some strict grammarians still prefer 'constitute' for this meaning.
