Plural of “zero”

The plural of zero is zeros (some dictionaries also accept zeroes).

Why

"Zero" traces a long path from Arabic "sifr" (empty, cipher) through Italian "zefiro" into English in the early 17th century, arriving alongside the mathematical concept of zero itself as it spread from the Arab world into Europe. As a relatively late, mathematically technical borrowing, it never settled firmly into either the older -oes pattern or a clean -s pattern, leaving both "zeros" and "zeroes" in active use.

"Zeros" has become the more common and more widely preferred plural in modern usage, especially in mathematics, computing, and everyday writing ("a million has six zeros"). "Zeroes" survives strongly as well, and notably as the standard spelling of the related verb form ("the sniper zeroes in on the target"), which keeps that spelling visible even as the plain noun plural drifts toward "zeros."

Usage note

For the plural noun, "zeros" is now the more commonly recommended form in most dictionaries and style guides. "Zeroes" remains correct and common, especially in British usage and in the fixed verb phrase "zeroes in on," which should always keep the -e regardless of which noun spelling you prefer elsewhere.

The mathematical concept of zero as a genuine number, rather than simply the absence of a quantity, developed independently in ancient India by around the 5th century CE, and Arab mathematicians and traders carried both the concept and the word into medieval Europe, where it met considerable resistance from scholars accustomed to Roman numerals. "Ground zero," originally a technical term for the point directly beneath a nuclear detonation, has since broadened figuratively to describe any starting point, a 20th-century extension that keeps "zero" fixed in the singular within that fixed phrase.

Common real mistakes

The clearest actual error is dropping the -e in the verb form ("zeros in on" instead of "zeroes in on"), since English verbs ending in a consonant-plus-o generally need the -es ending in the third person singular, a rule distinct from the noun plural debate entirely. Writers should also avoid confusing the mathematical "zero" with "null" or "nil," related but not perfectly interchangeable terms depending on the technical or sporting context.

The wider pattern

"Zero" shows how a single -o noun can develop two live, competing plurals without either one ever becoming a clear error, unlike "echo" or "veto," where the -es form is essentially mandatory, or "video" and "photo," where the plain -s form is essentially mandatory.
