Ch 2 · Lesson 41

How Spanish numbers work: up to 29

to by heart, then Spanish adds: is ten and six, veintidós twenty and two, each written as one word.

The short version

Veintidós is one word, is three

thirty-two
Why?

Spanish fuses sixteen to nineteen and twenty-one to twenty-nine into single words: , veintidós, veintiocho. From thirty-one the fusing stops and every number is tens, y, units. The y only ever joins tens to units, so 101 is , never .

These sixteen have no logic worth knowing: learn them. (11) is the trap, because it looks like the English word.

  • . - I'm eleven.
  • . - That's twelve euros.

Sixteen to nineteen: ten and six, as one word

From sixteen, Spanish starts adding. Sixteen is ten and six, squeezed into one word:

diez y seis became dieciséis
NumberBuilt fromWritten
16
17
18
19

The z of becomes c, and the y becomes i. takes an accent because the stress falls on the last syllable of a word ending in s:

  • . - My sister is sixteen.

Twenty to twenty-nine: one word again

fuses the same way, with its final e turning into i:

21 to 2324 to 2627 to 29
veintiunoveinticuatroveintisiete
veintidósveintiocho
veintitrésveintiséisveintinueve

Three carry an accent, the ones ending in a stressed syllable with an s: veintidós, veintitrés and veintiséis. With , and veintiún (the short form before a masculine noun), that is the whole accent family.

  • veintidós . - I'm twenty-two.

Going further: Thirty to ninety-nine: the y rule and the rest of the guide, when you want them. This lesson does not need them.
