Venetian school master ignores current big noise (5)
I believe the answer is:
titan
'big noise' is the definition.
(both can mean a big or important person)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for titan that I've seen before include "Giant god of Gr. myth" , "Giant god of Greek myth" , "Mythological giant" , "Very strong or important person" , "Person of great size" .)
