Figure of a fat lady (5)
I believe the answer is:
eight
'figure' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for eight that I've seen before include "Number; rowing boat" , "VIII" , "may be cut out of ice" , "Chaps having row" , "power of two" .)
