Did You Know?

It's no surprise that permeate means "to pass through something" - it was borrowed into English in the mid-17th century from the Latin permeatus, which comes from the prefix per- ("through") and the verb meare, meaning "to go" or "to pass." "Meare" itself comes from an ancient root that may have also led to Middle Welsh and Czech words meaning "to go" and "to pass," respectively. Other descendants of "meare" in English include "permeative," "permeable," "meatus" ("a natural body passage"), and the relatively rare "irremeable" ("offering no possibility of return").

Origin and Etymology of permeate

Latin permeatus, past participle of permeare, from per- through + meare to go, pass; akin to Middle Welsh mynet to go, Czech míjet to pass
