Antelope kicking tail shows style (4)
I believe the answer is:
elan
'style' is the definition.
(I know that style can be written as elan)
'antelope kicking tail' is the wordplay.
'antelope' becomes 'eland' (eland is a kind of antelope).
'kicking tail' means to remove the last letter.
'eland' with its last letter taken away is 'ELAN'.
'shows' acts as a link.
(Other definitions for elan that I've seen before include "Snap" , "Grass with edible grains" , "Dash, style" , "Dash in France" , "Flair and dash" .)
