The verb dissent means to offer an opinion that is different from other people.

Synonyms are balk, contradict, disagree, or protest.

The word origins from Old French (15th century) dissentir meaning “express a different or contrary opinion or feeling, with fold approval or consent”, and directly from Latin dissentire meaning “differ in sentiments, disagree, be at odds, contradict, quarrel”. It comes from dis- meaning “differently” plus sentire meaning “to feel, think”. The ecclesiastical sense of “refuse to be bound by the doctrines or rules of an established church” is from 1550s.
