compound adjective


compound adjective

High-quality and low-cost are examples of compound adjectives.


Two or more words (such as part-time or high-speed) that act as a single idea to modify a noun (a part-time employee, a high-speed chase). Also called phrasal adjective or compound modifier.

As a general rule, the words in a compound adjective are hyphenated when they come before a noun (a well-known actor) but not when they come after (The actor is well known).

Also, compound adjectives formed with an adverb ending in -ly (such as rapidly changing) are usually not hyphenated. (See Examples and Observations, below.)

  • "The influence of late-nineteenth-century political practice resonates through the early twentieth century, reminding scholars accustomed to viewing a sharp divide between nineteenth- and twentieth-century political practice--a divide that too often positions Progressives as the first stirrings of American politics--of the nineteenth-century roots of twentieth-century developments."

  • Hyphenation With Compound Adjectives
    "Interestingly, hyphenation is also used creatively to indicate that an idea that would normally be expressed by a phrase is being treated as a single word for communicative purposes because it has crystallised in the writer's mind into a firm, single concept. Thus, for example, the expression simple to serve is normally a phrase, just like easy to control. But it can also be used as a hyphenated word as in simple-to-serve recipe dishes (M&S Magazine 1992: 9). . . .

    "But for creative hyphenation you are unlikely to find anything more striking than this:
    [2.3] On Pitcairn there is little evidence of the what-we-have-we-hold, no-surrender, the Queen's-picture-in-every-room sort of attitude.
    (Simon Winchester in The Guardian magazine, 12 June 1993: 27; italics added to highlight the compounds)"
    (Francis Katamba, English Words: Structure, History, Usage, 2nd ed. Routledge, 2005)

    "Adverbs that do not end in -ly may take the hyphen to form a compound adjective. The reason is obvious. A fast-moving script suggests a roller coaster plot while a fast moving script might have pace but it is emotionally charged (i.e., emotionally moving) at the same time."
    (Bruce Grundy, So You Want to be a Journalist? Cambridge University Press, 2007)

    "A notable exception occurs when the first part of the compound adjective is an adverb that ends in -ly. In this case, the compound remains open, even when it is followed by the noun.
    The woman who met us in the lobby was beautifully dressed.
    A beautifully dressed woman met us in the lobby."
    (Oxford American Large Print Dictionary. Oxford University Press, 2008)

  • The Lighter Side of Compound Adjectives: Laser-Focused
    "Will somebody explain to me why every focus is now laser-focused? Lasers can guide, ignite, heat, drive and print, but focus? This is the hottest compound adjective around today, leaving all other focuses fuzzy. In Enron's 2000 annual report, the company claimed to be 'laser-focused on earnings per share,' at which point I should have become suspicious."
    (William Safire, The Right Word in the Right Place at the Right Time. Simon & Schuster, 2004)
