Sociable Greek, for example, one taking notes on the Crown (10)
I believe the answer is:
gregarious
'sociable' is the definition.
(I've seen this in another clue)
'greek for example one taking notes on the crown' is the wordplay.
I cannot quite see how this works, but
'greek' could be 'gr' (abbreviation for Greek) and 'gr' is found within the answer.
'example' could be 'eg' (short for 'exempli gratia', 'for example' in Latin) and 'eg' is found within the answer.
'one' could be 'o' (I've seen this in other clues) and 'o' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for gregarious that I've seen before include "Outgoing" , "tending to flock" , "Enjoying the company of others" , "Sociable" , "Living in flocks" .)
