Ridicule pirates going about with conspirator (3,6)
I believe the answer is:
guy fawkes
'conspirator' is the definition.
(I've seen this before)
'ridicule pirates going about with' is the wordplay.
'ridicule' becomes 'guy' (synonyms).
'pirates' becomes 'fakes' (I am not sure about this - if you are sure you should believe this answer much more).
'going about' means one lot of letters goes inside another.
'with' becomes 'w' (abbreviation).
'fakes' enclosing 'w' is 'fawkes'.
'guy'+'fawkes'='GUY FAWKES'
Can you help me to learn more?
(Other definitions for guy fawkes that I've seen before include "assassin" , "Plotter against James I" , "Gunpowder Plot hatcher" , "His effigy is burned on Nov 5 in England" , "17th-century conspirator" .)
