Model learnt about hotel delight (7)
I believe the answer is:
enthral
'delight' is the definition.
(enthralling is a kind of delighting)
'model learnt about hotel' is the wordplay.
'model' indicates an anagram.
'about' means one lot of letters goes inside another.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'learnt' with letters rearranged gives 'entral'.
'entral' going around 'h' is 'ENTHRAL'.
(Other definitions for enthral that I've seen before include "rivet" , "Bewitch" , "Fascinate - grip" , "Totally fascinate" , "Entrance" .)
