Outline design of hotel suite (10)
I believe the answer is:
silhouette
'outline' is the definition.
(I know that silhouette is a type of lineation)
'design of hotel suite' is the wordplay.
'design of' indicates an anagram (I've seen this in other clues).
'hotel'+'suite'='hotelsuite'
'hotelsuite' is an anagram of 'SILHOUETTE'.
(Other definitions for silhouette that I've seen before include "Outline figure" , "Profile of characters" , "Outline representation" , "Shadowy outline" , "image" .)
