Put down best ever (6)
I believe the answer is:
record
'put down' is the definition.
(I know that put down can be written as record)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for record that I've seen before include "The finest achievement" , "Set down in writing" , "List" , "history" , "a hole in one?" .)
