A person who disagrees or holds a different opinion, or something that differs or is different.
From Old French 'differer' and Latin 'differre,' meaning to carry apart or disagree. The suffix '-er' indicates an agent (one who differs). Latin 'dis-' means apart and 'ferre' means to carry.
A 'differer' is someone willing to stake a contrary position—historically, religious differers faced severe persecution, but they eventually shaped concepts of freedom of conscience.
