compound words
Examples of compound words in English.


In morphology, a compound word is made up of two or more words that express a single idea and function as a single word.

The most common types of compound words in English are compound nouns (e.g., cheeseburger), compound adjectives ("red-hot temper"), and compound verbs ("waterproof the deck").

The rules for spelling compound words are not consistent. Some compound words are written as a single word (eyeglasses), some as two (or more) hyphenated words (brother-in-law), and some as two (or more) separate words (soccer stadium).

  • Heads of Compound Words
    "One part of a compound word is usually clearly its head, in a general way able to represent the meaning of the whole compound. The heads of the various types of compound word are [in capital letters] in this list: bellBOY, spin-DRY, red HOT, inTO, and/OR. It can be seen that in English, the head of a compound word is always the last element, on the right-hand end. (This is not true of compound words in all languages, however.)"
    (James R. Hurford, Grammar: A Student's Guide. Cambridge University Press, 1994)
  • Dividing Compound Words
    "If you divide a compound word at the end of a line, place the hyphen between the elements of the compound (snow-mobile, not snowmo-bile)."

  • Metaphorical Compounds
    "Metaphors furnished with common household objects are figures of speech that we literally live with every day. Some of these comparisons are new, such as a couch potato, a phrase that compares lumpish watchers of television to lumpy potatoes: the longer couch potatoes sit, the deeper they put down their roots."
    (Richard Lederer, The Play of Words. Simon & Schuster, 1990)
  • Complex Compounds
    "It is possible to form a compound from two words one of which is itself a compound. For example, we can combine the compound law degree with the word requirement to get the complex compound law degree requirement. This compound can in turn be combined with changes to get law degree requirement changes, and so on. . . . [T]he process is essentially unlimited."
    (Bruce Hayes. Introductory Phonology. Wiley, 2009)
