Contend the figure has been entered in full (8)
I believe the answer is:
complete
'contend' is the definition.
(I know that complete is a kind of play)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for complete that I've seen before include "Whole, entire, uncut" , "Execute" , "Finished - whole" , "Perfect - finish" , "Bring to a satisfactory end" .)
