mys-

• mes-, mis-

From Old English mis-, from Proto-West Germanic *missa-, from Proto-Germanic *missa-. Reinforced by Old French mes-, ultimately from the same Proto-Germanic source.

While forms in -y- are definitely partly attributable to a desire to avoid the confusion of minims, they may have been encouraged by association with words such as mysterie.

• IPA^(key): /mis-/, /mɛs-/
