Yorkshireman (4)
I believe the answer is:
tyke
'yorkshireman' is the definition.
(tyke can mean someone from Yorkshire)
This is the entire clue.
(Other definitions for tyke that I've seen before include "Yorkshireman" , "Native of Yorkshire (informal)" , "Cheeky child or small dog" , "Cheeky tot" , "Mischievous child" .)
