Wonderful hospital department houses mean officer (14)
I believe the answer is:
superintendent
'officer' is the definition.
(I know that superintendent is a type of officer)
'wonderful hospital department houses mean' is the wordplay.
'wonderful' becomes 'super' (I've seen this before).
'hospital department' becomes 'ENT' (abbreviation for Ear, Nose and Throat department).
'houses' indicates putting letters inside.
'mean' becomes 'intend' (to intend to something is to mean it).
'super'+'ent'='superent'
'superent' placed around 'intend' is 'SUPERINTENDENT'.
(Other definitions for superintendent that I've seen before include "One who is in charge of an organisation" , "Police rank" , "Overseer; police officer" , "Police chief" , "Senior police officer" .)
