About 400 in Spanish
When speaking Spanish, 400 is expressed as cuatrocientos. The ordinal form — used for rankings, dates, and sequences — is cuadringentésimo.
Numerically, 400 is an even integer. In Spanish-speaking environments, 400 is the kind of number you'll hear and need to use regularly, from market prices to building floor numbers.
Mastering numbers like 400 is one of the most practical skills when learning Spanish. Unlike vocabulary that only applies in specific contexts, numbers come up constantly — in shops, on public transport, in conversations about time and money, and when meeting new people.
Learning Numbers in Spanish
What makes Spanish numbers challenging
Spanish numbers 0-15 are unique words requiring pure memorization. The contraction pattern changes at 16 (dieciséis) and again at 21 (veintiuno) and 31 (treinta y uno), creating three different combination styles. Phone numbers can be read in groups of varying size — digit-by-digit, pairs, or triples — and the style varies by speaker and country. The long scale in most Spanish-speaking countries means un billón = 1 trillion, a major trap in financial contexts. Regional pronunciation varies widely between Spain and Latin America.
Tips for learning Spanish numbers
Memorize 0-15 as a block, then learn the combining patterns for 16-19, 21-29, and 31+. Once you master these three patterns, the system is completely predictable. Practice with prices in euros or pesos for the most common real-world number encounters. For phone numbers, train with both digit-by-digit and group styles since speakers vary. Spanish number words are mostly transparent — cuarenta y cinco (45) literally means "forty and five" — making them intuitive once the base words are learned.
