Huge chaps in semi getting knocked out (7)
I believe the answer is:
immense
'huge' is the definition.
(I know that huge can be written as immense)
'chaps in semi getting knocked out' is the wordplay.
I cannot quite understand how this works, but
'chaps' could be 'men' (chap means a man) and 'men' is located in the answer.
an anagram of 'semi' is 'imse' which is present in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for immense that I've seen before include "Extremely large or great" , "Vast or enormous" , "Mammoth" , "'Gigantic, extensive (7)'" , "Unusually large or great" .)
