Recalled the French article written with panache (4)
I believe the answer is:
elan
'panache' is the definition.
(I know that panache can be written as elan)
'recalled the french article written with' is the wordplay.
'recalled' is a reversal indicator (to recall can mean to bring something back).
'the french' becomes 'le' ('the' in French).
'article' becomes 'an' (English indefinite article).
'written with' means one lot of letters go next to another.
'le' in reverse letter order is 'el'.
'el'+'an'='ELAN'
(Other definitions for elan that I've seen before include "Bounce" , "spirit" , "Combination of style and vigour" , "Vigour, panache" , "Grass with edible grains" .)
