Moor Hospital hosts event (7)
I believe the answer is:
saracen
'moor' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'hospital hosts event' is the wordplay.
'hospital' becomes 'san' (short for sanatorium).
'hosts' indicates putting letters inside (inserted letters are welcomed or hosted).
'event' becomes 'race' (race is a kind of event).
'san' placed around 'race' is 'SARACEN'.
Can you help me to learn more?
(Other definitions for saracen that I've seen before include "Arab (opposing the Crusaders)" , "Old Arab" , "Crusader's foe" , "British Army armoured people carrier" , "Arab or Muslim at time of the Crusades" .)
