ZERO in Spanish: CERO

Cero · noun · SEH-roh

Zero in Spanish is cero, a straightforward cognate that sounds similar to the English word. It is used in all numerical, mathematical, and everyday contexts just as zero is used in English. In casual speech, nada (nothing) can substitute when zero emphasizes an absence rather than a quantity. Cero is masculine (el cero) and invariable—it does not change form.

SEH-roh

La temperatura bajó a cero grados anoche.

The temperature dropped to zero degrees last night.

How Native Speakers Use Cero

Real example sentences across three contexts you'll actually run into.

The forecast says we'll reach zero degrees early this morning.

Cero grados is the standard way to express freezing point.

In sports, cero is used for scores, unlike English which sometimes says 'nil' or 'love.'

Avoid These Mistakes When Using Cero

Confusing cero with cerro

Incorrect: La temperatura llegó a cerro grados.

Correct: La temperatura llegó a cero grados.

Cero (one r) means zero. Cerro (double r) means hill or mountain. Mispronouncing or misspelling the word completely changes the meaning—you would be saying 'hill degrees' instead of 'zero degrees.'

Using nulo instead of cero for math

Incorrect: Cualquier número multiplicado por nulo es nulo.

Correct: Cualquier número multiplicado por cero es cero.

Nulo means null or void in a legal or technical sense. For mathematical zero, cero is always the correct term. Nulo is reserved for contexts like 'null and void' (nulo y sin efecto).

Why word lists alone don't stick

Memorizing a translation feels productive, but most learners forget 70% of what they studied within 48 hours. Vocabulary needs spaced repetition AND real-world exposure to transfer to long-term memory.

Save, review, repeat, stay consistent

Tap any word to save it. Parrot's spaced-repetition system surfaces it right before you'd forget, no manual flashcard creation. The watch, parrot back, save, review cycle turns recognition into fluency at 2.7x the speed of traditional study.

Common Questions About Zero in Spanish

How do you pronounce cero in Spanish?
Cero is pronounced SEH-roh in Latin America (where the c before e is an /s/ sound) and THEH-roh in most of Spain (where the c before e is a /θ/ sound, like the English 'th' in 'think'). The stress falls on the first syllable in both cases.
Is there a difference between cero and nada?
Cero is a number and is used in mathematical, scientific, and quantitative contexts (cero grados, cero puntos). Nada means 'nothing' and is used as an indefinite pronoun to indicate absence: no tengo nada (I have nothing). While they sometimes overlap in casual speech ('I have zero patience' could become no tengo nada de paciencia), they serve different grammatical functions.
How is cero used in phone numbers?
When dictating phone numbers in Spanish, cero is spoken as an individual digit: cero, uno, dos, tres, etc. Country codes and area codes that begin with zero use cero explicitly—for example, Spain's country code is 'cero, cero, tres, cuatro' (0034). This differs from some English dialects where 'oh' replaces 'zero.'
