Superhuman removing leader of ancient people (5)
I believe the answer is:
ionic
'of ancient people' is the definition.
The definition suggests a singular noun which matches the answer.
'superhuman removing leader' is the wordplay.
'superhuman' becomes 'bionic' (I've seen this in another clue).
'removing leader' means to remove the first letter.
'bionic' with its initial letter removed is 'IONIC'.
Can you help me to learn more?
(Other definitions for ionic that I've seen before include "Classical style" , "One of five classical orders of architecture" , "Classic order of architecture" , "Support (a weight)" , "Greek school" .)
