Etymology

The word "zero" entered English via French "zéro," derived from Italian "zero," which traces back to Medieval Latin "zephirum." This, in turn, comes from Arabic "ṣifr" (صفر), meaning "empty" or "nothing," a translation of Sanskrit "śūnya" (void). The Arabic term was initially used to denote the concept of emptiness in positional numeral systems, later evolving into the numerical symbol 0. The suffix "-o" in Italian/Latin stabilized the word's form in European languages.
