Addresses the French remedies containing testosterone (8)
I believe the answer is:
lectures
'addresses' is the definition.
(I know this)
'the french remedies containing testosterone' is the wordplay.
'the french' becomes 'le' ('the' in French).
'remedies' becomes 'cures' ('cure' can be a synonym of 'remedy').
'containing' means one lot of letters goes inside another.
'testosterone' becomes 't' (this might be a standard abbreviation which I don't know about).
'cures' placed around 't' is 'ctures'.
'le'+'ctures'='LECTURES'
Can you help me to learn more?
(Another definition for lectures that I've seen is " Discourses".)
