Man missing tackle? (6)
I believe the answer is:
eunuch
This clue could be a double definition.
'man' is the first definition.
(eunuch is a kind of man)
'missing tackle?' is the second definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for eunuch that I've seen before include "Castrated male, often guard in harem" , "Ineffective man" , "Powerless type" , "Man once employed as a harem guard" , "Castrated person" .)
