Etymology

cipher = ciph<zero> + er<noun suffix>

  • ciph (from Arabic ṣifr "zero, empty")
  • er (noun-forming suffix in English)

Etymology Origin:
The word "cipher" traces back to the Arabic ṣifr (صفر), meaning "zero" or "empty." It entered Medieval Latin as cifra, referring to the numeral zero, which was a groundbreaking concept in mathematics. Over time, the term evolved in European languages to denote coded writing (as codes often involved numerical substitutions). The sense of "a person of no importance" arose metaphorically from the idea of zero representing nothingness.
