Morphology

out + cold

The phrase combines 'out' (a common colloquial use meaning unconscious or knocked out) with 'cold' as an intensifier to mean completely unconscious; the meaning is clearly related to the constituent senses. However, the use of 'out' to mean unconscious is a phrasal/colloquial sense and the exact collocation may not be fully predictable to a B1 learner without exposure, so it is only partially transparent.

Etymology

Out cold may come from the image of a person lying 'out' in the open and becoming cold and very still after being knocked down. So 'out cold' came to mean 'completely unconscious' or in a very deep sleep.
