British venture I set up for powerful contractor? (6)
I believe the answer is:
biceps
'powerful contractor?' is the definition.
'biceps' can be an answer for 'contractor?' (I've seen this before). I am unsure of the 'powerful' bit.
'british venture i set up' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'venture' becomes 'spec' (I have seen 'commercial venture' mean 'spec' so perhaps 'venture' could also mean 'spec').
'set up' says the letters should be written in reverse (in a down clue, letters go up).
'spec'+'i'='speci'
'speci' written backwards gives 'iceps'.
'b'+'iceps'='BICEPS'
'for' is the link.
Can you help me to learn more?
(Other definitions for biceps that I've seen before include "Weightlifters use them" , "One operating arm" , "Large upper arm muscle" , "Arm workers" , "Contractor" .)
