Bond, in commercial hotel, overturned racket (8)
I believe the answer is:
adhesion
'bond' is the definition.
(I know that bond can be written as adhesion)
'commercial hotel overturned racket' is the wordplay.
'commercial' becomes 'ad' (abbreviation for advertisement).
'hotel' becomes 'h' (phonetic alphabet).
'overturned' is a reversal indicator.
'racket' becomes 'noise' (racket can mean a loud noise).
'noise' backwards is 'esion'.
'ad'+'h'+'esion'='ADHESION'
'in' acts as a link.
(Other definitions for adhesion that I've seen before include "Grip" , "Sticking fast" , "Stickiness" , "He's no aid to sticker" , "steady attachment" .)
