18 meanings of composition

Practice

  1. 1
    noununcountable
    The combination of elements or qualities present in someone or something.

    The committee's composition reflected a wide range of professional backgrounds.

    Geologists analyzed the chemical composition of the meteorite.

    Similarmakeup, constitution, structure, nature, character

    Note

    Applied to people, the word reaches into temperament. Frank Richards in 1932 notes that the milk of human kindness had not been left out of a character's composition, as if virtues were ingredients. Applied to groups, it means who belongs: a committee's composition, or a network's "mostly white composition" in 1982. A possessive is typical, as in his composition or the committee's composition.

  2. 2
    noununcountable
    The relative amounts of the different parts that make up a whole.

    The composition of the atmosphere is roughly four parts nitrogen to one part oxygen.

    Nutritionists describe the macronutrient composition of a meal as its balance of protein, fat, and carbohydrate.

    Similarmakeup, constitution, breakdown, profile

    Note

    Here the word means the recipe as much as the mix. In the King James Bible of 1611, the holy perfume may not be made "according to the composition thereof" for private use. In modern use it pairs with things that are measured, such as the composition of the atmosphere or of a meal. It usually takes of plus the whole being analyzed.

  3. 3
    nouncountable
    Something created as a work of art, such as a musical piece, a written text, or a painting.

    The pianist premiered an ambitious composition for two keyboards.

    Critics praised the composition as her most mature work to date.

    Similarwork, piece, opus, creation

    Note

    As a count noun it names the finished piece, such as a composition for two keyboards. As a mass noun it names the labor of making one. Jane Austen, in a letter of 1818, finds composition "impossible with a head full of joints of mutton." She means the act of writing, not any one book. Both uses sit comfortably side by side.

  4. 4
    nouncountable or uncountable
    A mixture or compound; the material that results from combining parts.

    The dentist filled the cavity with a tooth-colored composition.

    Early roofing materials were made from a tar-based composition.

    Similarcompound, mixture, composite, blend

    Note

    Shakespeare stretches the mixture to a person in King Lear. Kent calls the steward nothing but "the composition of a knave, beggar, coward, pandar." The insult works because the word usually names a blended substance, such as a filling or a roofing compound. The man becomes a mix of base ingredients. That figurative turn leads toward a person's general makeup.

  5. 5
    nouncountable
    A piece of writing on a particular subject, especially one written as a school exercise.

    Each student handed in a composition on a book they had read.

    His English composition explored the theme of friendship.

    Similaressay, paper, piece, assignment

  6. 6
    noununcountable
    The act or process of putting parts together; assembly.

    The composition of the symphony occupied him for years.

    The composition of the anthology involved selecting and ordering dozens of poems.

    Similarcreation, writing, assembly, compilation, construction

  7. 7
    nouncountable or uncountable
    The arrangement and flow of visual elements within a picture.

    The instructor critiqued the composition of each student's photograph.

    She balanced the composition by placing the horizon along the lower third.

    Similararrangement, layout, framing, design

    Note

    Painters and photographers judge a picture by how its line, shape, color and empty space sit in the frame, and how they lead the eye across it. Placing a horizon on the lower third rather than dead center is a rule of composition. A critique of a photograph often turns on composition before color or subject.

  8. 8
    noununcountable
    The formation of compound words by combining separate words.

    German is well known for productive composition, stringing several roots into a single long word.

    Through composition, "fire" and "fighter" combine to form "firefighter."

    Similarcompounding

    Note

    Linguists use the word as a near-synonym of compounding: fire plus fighter gives firefighter. The contrast to keep straight is with derivation, which builds words by attaching bound affixes such as -ness or un- to a root. Composition joins words that could each stand alone. German is the textbook case of productive composition.

  9. 9
    nouncountable or uncountable
    The operation of applying one function to the result of another.

    Function composition produces a new function from two existing ones.

    Students computed the composition of f and g by substituting one into the other.

    Note

    Mathematicians write it with a small circle: (g∘f)(x) = g(f(x)), read "g composed with f." Order matters. The function written second, f, is applied first. Composition is defined only when the codomain of the first function matches the domain of the second, so not every pair of functions can be composed.

  10. 10
    noununcountable
    The building up of a whole by combining simpler parts, in contrast to analysis, which breaks a whole into its parts.

    The proof relied on composition, combining known results into a single new theorem.

    Her method favored composition over analysis, building the model up from simple rules.

    Similarsynthesis

    Oppositeanalysis

    Note

    This is half of a pairing in which composition builds up and analysis takes apart. Isaac Newton's Opticks (1704) puts them in order: in investigating difficult things, analysis "ought ever to precede the method of composition." Synthesis names the same idea. Whichever word is used, it is defined by its opposite, and the two usually appear together.
