A prefix meaning “ill, mistaken, wrong, wrongly”

Etymology (EN): M.E., from O.E. mis-, cognate with M.Du. misse-, O.H.G. missa-, Ger. miss-, perhaps literally “in a changed manner,” and with a root sense of “difference, change” and thus possibly from PIE root *mei- “to change;” cf. Av. miθo- “perverted,” Skt. methati “changes, alternates, joins;” L. mutare “to change.”

Etymology (PE): Dož-, → dys-.
