Style adopted by Michelangelo
I believe the answer is:
elan
'style' is the definition.
(I've seen this before)
'adopted by michelangelo' is the wordplay.
'adopted by' says the answer is hidden in the clue.
'ELAN' can be found hidden inside 'michelangelo'.
(Other definitions for elan that I've seen before include "Grass with edible grains" , "Dash in Paris" , "Vivacity, dash" , "Panache - ardour" , "Vitality" .)
