The Italian mathematician Fibonacci (c. 1170–1250), who grew up in North Africa and is credited with introducing the decimal system to Europe, used the term "zephyrum". This became "zefiro" in Italian, and was then contracted to "zero" in Venetian. The Italian word "" was already in existence (meaning "west wind" from Latin and Greek "zephyrus") and may have influenced the spelling when transcribing Arabic "ṣifr".
