Mysteries of vernacular:
Zero,
a number that indicates an absence of units.
In order to understand the genesis of the word zero,
we must begin with the very origins of counting.
The earliest known archaeological evidence of counting
dates back approximately 37,000 years
and is merely a series of notches in bone.
It wasn't until around 2500 B.C.
that the first written number system
began to take form in Mesopotamia,
using the units one, ten, and sixty.
Fast forward another three millennia
to seventh century India
where mathematicians used a symbol dot
to distinguish between numbers
like 25, 205, and 250.
Employed as both a placeholder and a number,
this all-powerful dot eventually morphed
into the symbol we know today.
The word zero comes from the Arabic safira,
whose literal translation is empty.
Passing through Italian as zefiro,
zero came into English in the seventeenth century.
A second descendant of the Arabic root
was adopted into English through old French
as the word cipher.
Originally sharing the meaning empty with zero,
cipher later came to describe a code,
as early codes often used complicated substitutions
between letters and numbers.
From this shared empty origin,
zero continues to represent the number
that represents nothing.
