mastitis

the word 'mastitis' is a modern medical term constructed from classical greek components. the first part, 'mast-', originates from the greek 'mastos', which referred to the human breast or, by extension, the udder of an animal. the second part, '-itis', is a suffix borrowed directly from greek, where it was used to form adjectives indicating a connection or pertaining to something. in modern medical latin, it was repurposed as a noun-forming suffix specifically denoting diseases characterized by inflammation. thus, the term follows a perfectly logical, descriptive formula in scientific nomenclature, literally meaning "inflammation of the breast."

Structure: mast (breast) + itis (inflammation) mast (from greek mastos, meaning breast); itis (a new latin suffix from greek -itis, denoting inflammation or disease).
