Mathematics is the abstract study of topics encompassing quantity, structure, space, change, and other properties; it has no generally accepted definition.
The word mathematics comes from the Greek máthēma, which, in the ancient Greek language, means "what one learns", "what one gets to know", hence also "study" and "science", and in modern Greek just "lesson". The word máthēma is derived from μανθάνω (manthano), while the modern Greek equivalent is mathaino, both of which mean "to learn". In Greece, the word for "mathematics" came to have the narrower and more technical meaning "mathematical study", even in Classical times. Its adjective is mathēmatikós, meaning "related to learning" or "studious", which likewise further came to mean "mathematical".
