Pronunciation: Rhymes with Don whom see
Origin: Per the Online Etymology Dictionary, contumely comes from Latin
contumelia "an insult" via old French

harsh language or treatment arising from haughtiness and contempt;

Why use it? First, although it's a very rare word, it's relatively well-known from Shakespeare's Hamlet, Act III, scene 1:
For who would bear the whips and scorns of time,
Th' oppressor’s wrong, the proud
man’s contumely,
which is part of perhaps the most famous passage in all of Shakespeare - the "to be or not to be" soliloquy.
Second, it's more precise than "insult" or "scorn". It refers to a particular type of foul treatment.
