Royal hosted by Senior Dean, perhaps (6)
I believe the answer is:
skater
'royal' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'hosted by senior dean perhaps' is the wordplay.
'hosted by' means one lot of letters goes inside another.
'senior' becomes 'sr.' (similar in meaning).
'dean perhaps' becomes 'kate' (I can't justify this - if you can you should give a lot more credence to this answer).
'sr' placed around 'kate' is 'SKATER'.
Can you help me to learn more?
(Other definitions for skater that I've seen before include "Mover across ice" , "Glider on ice" , "Performer on ice" , "One sliding over ice" , "Winter sportsperson" .)
