The process of making something or someone diabolic; rendering wicked or devilish.
From diabolize + -ation (from Latin -atio), the American English spelling combining the verb with a noun-forming suffix that describes a process or result, similar to 'civilization' or 'civilization.'
The -ization suffix comes from ancient Greek and Latin, and became especially popular in American English during the 19th century for creating formal, technical-sounding nouns.
