Her leg was broken and had to be set (6)
I believe the answer is:
glenda
'her' is the definition.
'leg was broken and had to be set' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'leg' is 'gle' which is located in the answer.
an anagram of 'and' is 'nda' which is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for glenda that I've seen before include "-- Jackson, actress and former MP" , "- - Jackson, Hampstead MP" , "Girl" , "--- Jackson, Br. actress" .)
