Describing unsettled tribes (7)
I believe the answer is:
nomadic
'unsettled tribes' is the definition.
'nomadic' can be an answer for 'unsettled' (I've seen this before). I am not sure about the 'tribes' bit.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for nomadic that I've seen before include "It's just like Rover" , "Given to wandering like travellers or Bedouins" , "Not settled" , "Perhaps unsettling" , "constantly moving" .)
