Careworn crone Yank pushed around (7)
I believe the answer is:
haggard
'careworn' is the definition.
(synonyms)
'crone yank pushed around' is the wordplay.
I cannot quite see how this works, but
'crone' could be 'hag' (synonyms) and 'hag' is found in the answer.
The remaining letters 'gard' 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 haggard that I've seen before include "hollow-eyed appearance" , "Showing signs of overwork or suffering" , "Looking drawn and tired" , "Farm building for storing crops" , "Looking worn and exhausted" .)
