Marauding type of short woman married to ruler (6)
I believe the answer is:
viking
'marauding type' is the definition.
(the Vikings were known for their rampages)
'short woman married to ruler' is the wordplay.
'short woman' becomes 'vi' (short for Violet).
'married' means one lot of letters go next to another.
'to ruler' becomes 'king' (king is a kind of ruler).
'vi'+'king'='VIKING'
'of' acts as a link.
(Other definitions for viking that I've seen before include "Seafaring Scandinavian" , "Ancient Scandinavian adventurer" , "Norseman" , "One of the early invaders of Ireland" , "Scandinavian seafarer" .)
