Where does misclassified come from?
Misclassified was formed by adding the prefix mis-, meaning wrongly or incorrectly, to the past participle classified. Classify comes from Latin classificus, a past participle of classificare, meaning “to order or arrange into classes,” which in turn was based on classus, “a class or group.” The prefix mis- is used in English to reverse or spoil the intended meaning of a verb, as in misrepresent or misspell.
