Usage
What does ot- mean? Ot- is a combining form used like a prefix meaning “ear.” It is often used in medical terms, especially in anatomy and pathology. Ot- comes from the Greek oûs, meaning “ear.” Related to the Greek oûs is English’s own word ear; so is the Latin word for ear, auris, which is the ultimate source of such words as aural. Learn more about oûs at our entry for otic, an adjective used in anatomy meaning “of or relating to the ear.”Ot- is a variant of oto-, which loses its -o- when combined with words or word elements beginning with vowels.
