Flair in ornate language (4)
I believe the answer is:
elan
'flair' is the definition.
(I know that flair can be written as elan)
'in ornate language' is the wordplay.
'in' says the answer is hidden in the clue.
'ELAN' is hidden in the letters of 'ornate language'.
(Other definitions for elan that I've seen before include "Stylish verve" , "Snap" , "Vigour, panache" , "'Panache, flair (4)'" , "Stylishness" .)
