Regaled an inspiring figure on the day (6)
I believe the answer is:
amused
'regaled' is the definition.
(I've seen this in another clue)
'an inspiring figure on the day' is the wordplay.
'an' becomes 'a'.
'inspiring figure' becomes 'muse' (I can't explain this - if you can you should give a lot more credence to this answer).
'on' says to put letters next to each other.
'the day' becomes 'd' (abbreviation for day).
'a'+'muse'+'d'='AMUSED'
Can you help me to learn more?
(Other definitions for amused that I've seen before include "Pleasantly occupied" , "Victoria reputedly wasn't" , "Made (someone) laugh" , "Medusa (anag)" , "Mildly diverted or entertained" .)
