Spanish Numbers 1-100: Los Números

Spanish numbers from one to twenty spelled out individually, then the tens up to one hundred, with the pattern that makes the rest easy to guess.

Numbers are pure utility vocabulary: prices, ages, phone numbers, times, addresses. Spanish numbers 1-15 are worth memorizing individually. After that, a pattern takes over that does most of the work for you.

One Through Twenty

  • uno: one
  • dos: two
  • tres: three
  • cuatro: four
  • cinco: five
  • seis: six
  • siete: seven
  • ocho: eight
  • nueve: nine
  • diez: ten
  • once: eleven
  • doce: twelve
  • trece: thirteen
  • catorce: fourteen
  • quince: fifteen
  • dieciséis: sixteen
  • diecisiete: seventeen
  • dieciocho: eighteen
  • diecinueve: nineteen
  • veinte: twenty

The Tens

  • treinta: thirty
  • cuarenta: forty
  • cincuenta: fifty
  • sesenta: sixty
  • setenta: seventy
  • ochenta: eighty
  • noventa: ninety
  • cien: one hundred

The Pattern That Does the Rest

From sixteen through twenty-nine, Spanish numbers are written as one word: dieciséis is literally diez y seis (“ten and six”) fused together, and the same logic gives you veintiuno (21), veintidós (22), and on through veintinueve (29).

From thirty-one onward, the pattern switches to three separate words joined by y (and): treinta y uno (31), cuarenta y cinco (45), setenta y ocho (78). Once you know the tens above and the numbers one through nine, you can build almost any number up to ninety-nine without memorizing anything new.
