Morphology

as + cool + as + a + cucumber

The simile pattern 'as ... as ...' plus knowledge of 'cool' (calm) and 'cucumber' (a cool vegetable) gives a learner a plausible route to infer a meaning related to being very calm. However, the link that a cucumber implies calmness is a culturally based metaphorical extension (temperature → composure) and may not be immediately obvious to all B1 learners without prior exposure. Because the compositional structure helps but the specific figurative association is not fully predictable, this is best classed as semi-transparent.

Etymology

The idiom as cool as a cucumber comes from the image of a cucumber staying cool inside even on hot days, so the vegetable became a picture of calm. That's why saying someone is as cool as a cucumber means they are 'very calm' and not 'nervous'.
