Hotel meal with no starter giving you the hump (5)
I believe the answer is:
hunch
'the hump' is the definition.
(thesaurus)
'hotel meal with no starter' is the wordplay.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'meal' becomes 'lunch' (lunch is a kind of meal).
'with no starter' means to remove the first letter.
'lunch' with its initial letter removed is 'unch'.
'h'+'unch'='HUNCH'
'giving you' is the link.
(Other definitions for hunch that I've seen before include "Intuitive guess" , "Guess -- sit with bad posture" , "Idea based on intuition" , "Lump - intuitive feeling" , "Premonition; hump" .)
