What's noble about extremely acidic Greek commander? (8)
I believe the answer is:
xenophon
'extremely acidic greek commander?' is the definition.
The definition suggests a singular noun which matches the answer.
'what's noble about' is the wordplay.
I cannot really understand how this works, but
'about' could be 'on' and 'on' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for xenophon that I've seen before include "Greek writer (Anabasis)" , "Ancient Greek general" , "Greek historian (Anabasis)" .)
