Leaving hotel, warm welcome for jealous husband (7)
I believe the answer is:
othello
'jealous husband' is the definition.
(I've seen this before)
'leaving hotel warm welcome' is the wordplay.
'leaving' is a deletion indicator.
'hotel' becomes 'h' (phonetic alphabet).
'warm' becomes 'hot' (synonyms).
'welcome' becomes 'hello' (both are greetings).
'hot' with 'h' removed is 'ot'.
'ot'+'hello'='OTHELLO'
'for' acts as a link.
(Other definitions for othello that I've seen before include "Jealous character" , "Shakespeare hero" , "Dramatic Moor" , "Shakespearean Moor" , "He killed his wife Desdemona" .)
