Perhaps one judge to be included (6)
I believe the answer is:
figure
'perhaps one' is the definition.
(I know that 1 is a type of figure)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for figure that I've seen before include "Symbol representing a number" , "Symbol, numeral" , "Judge to be probable, estimate" , "Diagram or digit" , "form" .)
