About to be dismissed by group of women, being a poor performer (3)
I believe the answer is:
ham
'poor performer' is the definition.
(I've seen this in another clue)
'about to be dismissed by group of women being a' is the wordplay.
'about' indicates putting letters inside.
'to be dismissed by group of women' becomes 'hm' (I can't explain this - if you can you should believe this answer much more).
'being a' becomes 'a'.
'hm' enclosing 'a' is 'HAM'.
Can you help me to learn more?
(Other definitions for ham that I've seen before include "Meat; radio operator" , "Meat for actor who overdoes it" , "Dried pig thigh" , "Food" , "Meat served in sandwiches" .)
