Hung about, making Nigel terribly embarrassed (8)
I believe the answer is:
lingered
'hung about' is the definition.
The answer and definition can be both to do with motion as well as being past participle verbs.
Maybe you can see an association between them that I can't see?
'nigel terribly embarrassed' is the wordplay.
'terribly' indicates an anagram.
'embarrassed' becomes 'red' (someone may blush or go red when embarrassed).
'nigel' with letters rearranged gives 'linge'.
'linge'+'red'='LINGERED'
'making' acts as a link.
Can you help me to learn more?
(Other definitions for lingered that I've seen before include "left behind" , "Stayed on, hung around" , "Dallied" , "Hung on, dawdled" , "Loitered" .)
