Merciless type of woman from Takeaway (8)
I believe the answer is:
ruthless
'merciless' is the definition.
('ruthless' can be similar in meaning to 'merciless')
'type of woman from takeaway' is the wordplay.
I cannot quite see how this works, but
'woman' could be 'ruth' and 'ruth' is found within the answer.
The remaining letters 'less' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for ruthless that I've seen before include "hard" , "Showing no mercy" , "Hard-hearted" , "devoid of compassion" , "Having no mercy like hustlers" .)
