Zero
The word zero came into the English language via French zéro from the Italian zero, a contraction of the Venetian zevero form of Italian zefiro via ṣafira or ṣifr.[1]
In pre-Islamic time the word ṣifr (Arabic صفر) had the meaning "empty".[2] Sifr evolved to mean zero when it was used to translate śūnya (Sanskrit: शून्य) from India.[2]
The first known English use of zero was in 1598.[3]
The Italian mathematician Fibonacci (c. 1170 – c. 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 zefiro was already in existence (meaning "west wind" from Latin and Greek Zephyrus) and may have influenced the spelling when transcribing Arabic* ṣifr*.[4]
