Freelancer has vigour and style (4)
I believe the answer is:
elan
'vigour and style' is the definition.
(elan is style or elegance)
'freelancer has' is the wordplay.
'has' indicates a hidden word.
'ELAN' can be found hidden inside 'freelancer'.
(Other definitions for elan that I've seen before include "Vitality" , "spirit" , "Stylish verve" , "Vivacity, panache" , "Energy, style and enthusiasm" .)
