Origin Of Phrase "Cool As A Cucumber"


Did you know? The inside of a cucumber is almost 20 degrees cooler than the outside air? Well, this could be the origin of this idiomatic expression.

This common idiom comes from the cool and refreshing attributes of cucumber. Cucumbers are always fresh, calm, and green. The inside of cucumbers stays fresher than the air, even in hot weather. So the simile is formed by referring to the coldness of cucumbers. Mostly made of water, cucumbers are cool to the touch.

But the meaning of the word "cool" in the expression doesn't indicate a low temperature. It means to be undisturbed, self-confident, and calm.

British poet John Gay recorded the phrase for the first time in verse. In 1732, he wrote the poem 'New Song on New Similies':

My passion is as mustard strong;

I sit all sober, sad;

Drunk as a piper all day long,

Or like a March-hare mad.

Round as a hoop, the bumpers flow;

I drink, yet can't forget her;

For, though as drunk as David's sow,

I love her still the better.

Pert as a pear-monger I'd be,

If Molly were but kind;

Cool as a cucumber could see

The rest of the womankind.
