'around' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?

'number in coma possibly wandering' is the wordplay.
'number' becomes 'n' (n can represent any number).
'in' is an insertion indicator.
'possibly' indicates an anagram.
'wandering' becomes 'di' (I can't explain this - if you can you should give a lot more credence to this answer).
'coma' anagrammed gives 'omac'.
'omac' enclosing 'di' is 'omadic'.
'n'+'omadic'='NOMADIC'
