Style seen in Yuletide land (4)
I believe the answer is:
elan
'style' is the definition.
(I know that style can be written as elan)
'in yuletide land' is the wordplay.
'in' says the answer is hidden in the clue.
'ELAN' can be found hidden inside 'yuletide land'.
'seen' is the link.
(Other definitions for elan that I've seen before include "Dash in Paris" , "Stylish verve" , "Flair and dash" , "Dash in France" , "Stylishness" .)
