Runaway vs. run away

Runaway works as a noun (meaning someone or something that has run away) and an adjective (meaning out-of-control, unrestrained, or escaped), but it does not function as a verb. If you need a verb meaning to flee or to escape, use the two-word phrasal verb run away.

Run away is just one of many phrasal verbs with corresponding one-word nouns/adjectives. Check up, work out, and blow up are a few other examples. The one word forms almost never become verbs in standard usage.

  1. If native speakers aren’t sure of the spelling, they can rely on this pronunciation tip.

    “¢ The phrasal verb is stressed on the second element (the preposition/particle): to run aWAY
    “¢ The noun compound is stressed on the first element (the first noun): a RUNaway

    This is true for all phrasal verb vs. noun compound pairs: to follow up vs. the follow-up, to sit in vs. a sit-in, etc.

    I have to teach this to my non-native speaking clients since they didn’t grow up “knowing” the correct pronunciation.  Native speakers say it right, just don’t usually spell it right.
