Head of Dorchester hotel can supply various events (9)
I believe the answer is:
decathlon
'head of dorchester hotel can supply various events' is the definition.
I can't judge whether this definition defines the answer.
'head of dorchester hotel can supply' is the wordplay.
'head of' suggests taking the first letters.
'supply' indicates an anagram (in a supple way).
The initial letter of 'dorchester' is 'd'.
'hotel'+'can'='hotelcan'
'hotelcan' with letters rearranged gives 'ecathlon'.
'd'+'ecathlon'='DECATHLON'
Can you help me to learn more?
(Other definitions for decathlon that I've seen before include "Olympic athletics event" , "Event, or events" , "Competition comprising ten events" , "Sporting event with 10 disciplines" , "Athletic event" .)
