Son chilled outside hotel, getting educated (8)
I believe the answer is:
schooled
'educated' is the definition.
('school' can be a synonym of 'educate')
'son chilled outside hotel' is the wordplay.
'son' becomes 's'.
'chilled' becomes 'cooled' ('cool' can be a synonym of 'chill').
'outside' is an insertion indicator.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'cooled' going around 'h' is 'chooled'.
's'+'chooled'='SCHOOLED'
'getting' is the link.
(Other definitions for schooled that I've seen before include "Educated" , "Trained" .)
