napping, to be caught/catch
To be surprised off guard, taken unawares. This term began life in the sixteenth century as to be taken napping. “Take Nappynge as Mosse toke his Meare” was the title of a 1569 ballad. The term was included in John Ray’s proverb collection of 1670, in which Ray commented, “Who this Moss was is not very material to know. I suppose some such man might find his mare dead, and taking her to be only asleep, might say, ‘Have I caught you napping?’” Yet Shakespeare and other sixteenth-century writers used the phrase in the modern sense of taking someone unawares; “Nay, I have ta’en you napping, gentle love,” Tranio says to Bianca (The Taming of the Shrew, 4.2).
