Counting from 0 to 10 in Spanish

0 : cero
1 : uno
2 : dos
3 : tres
4 : cuatro
5 : cinco
6 : seis
7 : siete
8 : ocho
9 : nueve
10 : diez

Note :

All the above numbers are invariable, except “uno”.

Examples :

• Una mesa (1 table)
• Cuatro manzanas (4 apples)
• Siete días (7 days)

“Uno” also turns into “un” before a masculine noun.

“Uno hombre” thus becomes “un hombre” (1 man).

12 : doce
13 : trece
14 : catorce
15 : quince
16 : dieciséis
17 : diecisiete
18 : dieciocho
19 : diecinueve

Counting from 21

21, 22, 23, 24, 25, 26, 27, 28, 29, 30 : veintiuno, veintidós, veintitrés, veinticuatro, veinticinco, veintiséis, veintisiete, veintiocho, veintinueve, treinta
31, 32,…, 40 : treinta y uno, treinta y dos,…, cuarenta
41, 42,… : cuarenta y uno, cuarenta y dos,…
50, 60, 70, 80, 90 : cincuenta, sesenta, setenta, ochenta, noventa
100 : cien
101, 102,… : ciento uno, ciento dos,…
200, 300, 400, 500, 600, 700, 800, 900 : doscientos (doscientas), trescientos (trescientas), cuatrocientos (cuatrocientas), quinientos (quinientas), seiscientos (seiscientas), setecientos (setecientas), ochocientos (ochocientas), novecientos (novecientas)
1000, 2000,… : mil, dos mil,…

Notes :

The conjunction “y” (and) is only used between tens and units (e.g. 45 = cuarenta y cinco).

“Ciento” is apocopied as “cien” before a noun, before “mil” and before “million”.

Ex : cien mil : 100 000

“Veintiuno” is apocopied as “veintiun” before a masculine noun.

All the numbers are invariable except the ones composed with the digit “uno” (digit which, for reminder, is not invariable).

Numbers from 200 to 900 are not invariable either and agree in gender.

“mil” does not agree if used as a number (it does agree if used as a common noun).

Examples :

• 2020 : dos mil veinte
• 1564 : mil quinientos sesenta y cuatro
• 752 : setecientos cincuenta y dos

Some complements

Una decena (about ten)
Una docena (a dozen)
Una quincena (about fifteen)
Una veintena (about twenty)
Un centenar (a hundred)
Un millar (a thousand)
Un millón (one million)

Examples :

• Quisiera una docena de ostras por favor. (I would like a dozen oysters please).
