Old geometer too befuddled to graph, say (10)
I believe the answer is:
pythagoras
'old geometer too' is the definition.
I can't judge whether this defines the answer.
'befuddled to graph say' is the wordplay.
'befuddled' indicates anagramming the letters.
'to'+'graph'+'say'='tographsay'
'tographsay' with letters rearranged gives 'PYTHAGORAS'.
Can you help me to learn more?
(Other definitions for pythagoras that I've seen before include "Ay to graphs (anag) - 21 3 17 theorist" , "Greek philosopher and mathematician, d. c 500 BC" , "Ancient mathematician" , "Greek philosopher/mathematician" , "Greek with a theorem" .)
