Displaying heroic style in full? Not in full (7)
I believe the answer is:
homeric
'full? not in full' is the definition.
I can't tell whether this definition defines the answer.
'displaying heroic style in' is the wordplay.
'displaying' becomes 'm' (I can't explain this - if you can you should give a lot more credence to this answer).
'style' is an anagram indicator (style can mean to shape or design).
'in' means one lot of letters goes inside another.
'heroic' with letters rearranged gives 'hoeric'.
'm' inserted inside 'hoeric' is 'HOMERIC'.
Can you help me to learn more?
(Other definitions for homeric that I've seen before include "of old poet" , "Relating to Iliad and Odyssey" , "Large-scale" , "Like unrestrained laughter" , "In style of, eg, the Iliad" .)
