Scot's sound in mind? On the contrary, one wanders a lot (5)
I believe the answer is:
nomad
'scot's sound' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'in mind? on the contrary one wanders a lot' is the wordplay.
'in' is an insertion indicator.
'mind? on the contrary' becomes 'nod' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'one wanders' indicates anagramming the letters.
'lot' becomes 'm'.
'a'+'m'='am'
'am' is an anagram of 'ma'.
'nod' going around 'ma' is 'NOMAD'.
Can you help me to learn more?
(Other definitions for nomad that I've seen before include "Traveller with no permanent home" , "someone who can't settle" , "one of those with no fixed home" , "Roamer" , "Itinerant" .)
