Brawn from church in the course of outings (7)
I believe the answer is:
triceps
'brawn' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'church in the course of outings' is the wordplay.
'church' becomes 'ce' (abbreviation for Church of England).
'in the course of' means one lot of letters goes inside another.
'outings' becomes 'trips' (I've seen this before).
'ce' put into 'trips' is 'TRICEPS'.
'from' is the link.
Can you help me to learn more?
(Other definitions for triceps that I've seen before include "Muscle at the back of the upper arm" , "one can't bend the elbow!" , "Green citrus fruit" , "Upper-arm muscle" , "Source of uplifting strength" .)
