I'd mentioned being given some regard (4)
I believe the answer is:
eyed
'given some regard' is the definition.
Although both the answer and definition are past participle verbs, I can't see how one could define the other.
'i'd mentioned' is the wordplay.
'mentioned' indicates a 'sounds like' (homophone) clue.
'id' sounds like 'EYED'.
'being' is the link.
Can you help me to learn more?
(Other definitions for eyed that I've seen before include "examined" , "Stared at" , "Looked at, warily perhaps" , "Watched with interest" , "Viewed" .)
