Outline conversion of hotel suite (10)
I believe the answer is:
silhouette
'outline' is the definition.
(I know that silhouette is a type of outline)
'conversion of hotel suite' is the wordplay.
'conversion of' indicates anagramming the letters (I've seen 'conversion' mean this).
'hotel'+'suite'='hotelsuite'
'hotelsuite' anagrammed gives 'SILHOUETTE'.
(Other definitions for silhouette that I've seen before include "Profile of characters" , "Outline representation" , "Outline figure" , "Shadowy outline" , "image" .)
