Flair shown by the old man capturing an iconic fighter (7)
I believe the answer is:
panache
'flair' is the definition.
(I know that flair can be written as panache)
'the old man capturing an iconic fighter' is the wordplay.
'the old man' becomes 'pa' (both can mean father).
'capturing' is an insertion indicator.
'iconic fighter' becomes 'che' (I've seen this before. I am not sure about the 'iconic' bit.).
'pa' going around 'an' is 'pana'.
'pana'+'che'='PANACHE'
'shown by' is the link.
Can you help me to learn more?
(Other definitions for panache that I've seen before include "Flamboyant sense of style" , "stylish carriage" , "A confident stylish manner" , "Dash and verve" , "'Dash, flair (7)'" .)
