This week, we’re looking at one of my favourite French expressions: ‘une grosse légume’.
‘Grosse légume’.
How to pronounce it:
Grow-ss lay-goom.
What it means in English:
Although it literally translates as ‘large vegetable’, it’s a French slang term that’s used to describe someone who’s very powerful or influential, a bit like ‘big cheese’ or ‘bigwig’ in English.

Where does it come from?
According to the website Expressions Françaises, ‘une grosse légume’ originated in the middle of the nineteenth century. This was when the word ‘légume’ was feminine rather than masculine, as it is is today.
At the time, it was a slang term for a senior army officer.

How to use it in a sentence:
‘M. Burns est une grosse légume.’
English translation:
‘Mr. Burns (from The Simpsons) is a big cheese.’
Similar words:
Un gros bonnet = A big cheese (literally: a big hat).
Un gros poisson = A bigwig (literally: a big fish).
Une huile = A V.I.P./a ‘big cheese’ (literally: an oil).
