Ring five times for a symbol (7)
I believe the answer is:
olympic
'ring five' is the definition.
Although both the answer and definition are adjectives, I don't understand how one could define the other.
'times for a symbol' is the wordplay.
I cannot really understand how this works, but
'symbol' could be 'pi' (pi is a kind of symbol) and 'pi' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for olympic that I've seen before include "International athletic event" , "Of ancient Greek site (of original games)" , "Games, quadrennial in occurrence" , "Of four-year games" , "of certain events" .)
