Came down to earth about blokes getting nutrition (7)
I believe the answer is:
aliment
'nutrition' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'came down to earth about blokes' is the wordplay.
'came down to earth' becomes 'alit' (I've seen this before).
'about' is an insertion indicator.
'blokes' becomes 'men' (bloke can informally mean a man).
'alit' placed around 'men' is 'ALIMENT'.
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for aliment that I've seen before include "Old word for food" , "Something which nourishes - meal tin (anag)" , "Sustenance" , "Nourishment" .)
