I love to go out dancing. (OALD)
When I came across this sentence, I recollected the man, Cheo Yong, who saw four legs on his bed over 1,130 years ago, when he came back late. After that, singing “two are mine, two are who’s? Though originally mine, what should I do, after deprived,” he went out, dancing. (This song very famous, every Korean middle school student learns the old lyrics in Korean text books.)
But I can find ‘go out dancing’ is interpreted, on Korean websites, into ‘go outside to dance.’ Is it an idiom? Can the sentence in OALD be interpreted ‘go outside, dancing,’ as the dancing of the doomed guy who saw four legs in A.D.879.
