Wanderer who'll show willingness to keep mum? (5)

Ross

I believe the answer is:

nomad

I'm a little stuck... Click here to teach me more about this clue!

'wanderer' is the definition.
(I know that Nomad is a type of wanderer)

'who'll show willingness to keep mum?' is the wordplay.
I cannot quite understand how this works, but
'mum?' could be 'ma' (ma can mean mother) 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 explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for nomad that I've seen before include "Wanderer" , "drifter" , "Roving person" , "one must move on" , "Unsettled character" .)

I've seen this clue in the Evening Standard.
