Initially Equity underserved northerners, casting such men without parts (7)
I believe the answer is:
eunuchs
'men without parts' is the definition.
I can't judge whether this definition defines the answer.
'initially equity underserved northerners casting such' is the wordplay.
'initially' indicates taking the first letters.
'casting' is an anagram indicator.
The initial letters of 'equity underserved northerners' is 'eun'.
'such' with letters rearranged gives 'uchs'.
'eun'+'uchs'='EUNUCHS'
Can you help me to learn more?
(Other definitions for eunuchs that I've seen before include "Harem guards" , "They're harmless to women" , "Men cut out for work in harems?" , "deprived men" , "Castrati" .)
