Leading character in Troy, as often written by Homer? (3)
I believe the answer is:
tau
'leading character' is the definition.
'tau' can be an answer for 'character' (tau is a kind of character). I'm unsure of the 'leading' bit.
'troy as often written by homer?' is the wordplay.
'troy' becomes 't'.
'as often written by homer?' becomes 'au' (I am not sure about this - if you are sure you should believe this answer much more).
't'+'au'='TAU'
'in' is the link.
Can you help me to learn more?
(Other definitions for tau that I've seen before include "Greek character" , "19th letter of the Greek alphabet" , "Greek letter; cross" , "Homeric character" , "A subatomic particle" .)
