Homer is involved in tales of this? (7)
I believe the answer is:
heroism
'tales of this?' is the definition.
The definition suggests a singular noun which matches the answer.
'homer is involved' is the wordplay.
'involved' indicates an anagram (involved can mean confusing or complex).
'homer'+'is'='homeris'
'homeris' anagrammed gives 'HEROISM'.
'in' is the link.
Can you help me to learn more?
(Other definitions for heroism that I've seen before include "Courageous quality" , "Gallantry" , "brave action" , "Is Homer involved in brave behaviour?" , "Very brave conduct or act of valour" .)
