Could get angry, I see, following refusal to describe people roaming around (7)
I believe the answer is:
nomadic
'roaming around' is the definition.
'nomadic' can be an answer for 'roaming' (I've seen this before). I'm not sure about the 'around' bit.
'could get angry i see following refusal to describe people' is the wordplay.
I cannot quite see how this works, but
'angry' could be 'mad' (similar in meaning) and 'mad' is present in the answer.
'i' is within the answer.
'see' could be 'c' (the word for the letter, according to Chambers) and 'c' is located in the answer.
'refusal' could be 'no' (it's a no) and 'no' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for nomadic that I've seen before include "Not settling" , "Given to wandering, like travelling tribes" , "It's just like Rover" , "Migratory" , "Itinerant" .)
