Charm learnt after a fashion going round hospital (7)
I believe the answer is:
enthral
'charm' is the definition.
(enthral can mean to charm or captivate)
'learnt after a fashion going round hospital' is the wordplay.
'after a fashion' indicates an anagram (letters re-fashioned).
'going round' means one lot of letters goes inside another (some letters go around others).
'hospital' becomes 'H' (abbreviation for hospital).
'learnt' with letters rearranged gives 'entral'.
'entral' going around 'h' is 'ENTHRAL'.
(Other definitions for enthral that I've seen before include "Hold captive" , "absorb" , "be captivating?" , "hypnotise" , "Fascinate - grip" .)
