Tribesman who’ll show encouragement embracing his mum (5)
I believe the answer is:
nomad
'tribesman who'll show encouragement embracing his' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'mum' is the wordplay.
I cannot really understand how this works, but
'mum' could be 'ma' (synonyms) and 'ma' is found within the answer.
The remaining letters 'nod' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for nomad that I've seen before include "someone who can't settle" , "One travels from place to place with no permanent home" , "Unsettled character" , "Person always on the move" , "Itinerant" .)
