Did you know?

It's no surprise that permeate means "to pass through something"—it was borrowed into English in the 17th century from 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").
