Emphasise current coin you took in, we hear (10)
I believe the answer is:
accentuate
'emphasise' is the definition.
(synonyms)
'current coin you took in we hear' is the wordplay.
I cannot really see how this works, but
'current' could be 'ac' (alternating current) and 'ac' is found in the answer.
'coin' could be 'cent' (cent is a kind of coin) and 'cent' is found within the answer.
'you' could be 'u' (homophones) and 'u' is present in the answer.
'took' could be 'ate' (eating is a kind of taking) and 'ate' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for accentuate that I've seen before include "Stress" , "Draw attention to" , "Make more prominent" , "Emphasise" .)
