Morphology

three-dog + night

The phrase is built from transparent parts ('three' + 'dog' + 'night') and evokes a literal image — a night so cold you need three dogs for warmth — so a learner could potentially infer the basic sense. However, understanding that this image conventionalises to mean 'extremely cold night' relies on cultural/figurative knowledge and is not a standard compositional pattern, making the relation only partially predictable to B1 learners.

Etymology

The phrase three-dog night comes from people who slept with dogs in very cold cabins to stay warm. If they needed three dogs in the bed, the night was extremely cold, so the phrase means 'an extremely cold night'.
