Effective separate WC when camping, perhaps (6)
I believe the answer is:
potent
'effective' is the definition.
(associated in meaning)
'separate wc when camping perhaps' is the wordplay.
I cannot really see how this works, but
'camping' could be 'tent' (I've seen this in other clues) and 'tent' is located in the answer.
The remaining letters 'po' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for potent that I've seen before include "Powerful like strong drink" , "Forceful" , "Intoxicating" , "Mighty" , "Strong in operation" .)
