The suffix -clast is of Greek origin, it means break. An "iconoclast" is a critic, someone who tries to break an institution by attacking it. To provide further help, a "fanatic" is someone who cares deeply about something; "vendor," "purveyor," and "peddler" are all synonyms - they all mean seller.

"Anarchy" means chaos, the lack of a political order. As a word it can be easily broken down to its component parts. The prefix an- means without and the root -arch- means leader, chief. So "anarchy" is without a leader, without a government, the lack of political order.
