Numbers 1 to 100

Numbers are essential for everyday communication — telling time, shopping, giving your phone number, stating your age, and countless other situations. Spanish numbers follow a logical system, but there are some irregular forms you need to memorise.

Numbers 0–15: The Irregular Group

The numbers from zero to fifteen must be memorised individually, as each has its own unique form.

Number	Spanish	Pronunciation
0	cero	"SEH-roh"
1	uno	"OO-noh"
2	dos	"dohs"
3	tres	"trehs"
4	cuatro	"KWAH-troh"
5	cinco	"SEEN-koh"
6	seis	"says"
7	siete	"SYEH-teh"
8	ocho	"OH-choh"
9	nueve	"NWEH-beh"
10	diez	"dyehs"
11	once	"OHN-seh"
12	doce	"DOH-seh"
13	trece	"TREH-seh"
14	catorce	"kah-TOHR-seh"
15	quince	"KEEN-seh"

Tip: Notice that 11–15 do not follow the "dieci-" pattern that 16–19 use. These five numbers (once, doce, trece, catorce, quince) must simply be memorised.

Numbers 16–19: The "Dieci-" Pattern

Numbers 16–19 are formed by combining dieci- (a contraction of diez y, meaning "ten and") with the units digit. They are written as one word.

Number	Spanish	Breakdown	Pronunciation
16	dieciséis	dieci + seis	"dyeh-see-SAYS"
17	diecisiete	dieci + siete	"dyeh-see-SYEH-teh"
18	dieciocho	dieci + ocho	"dyeh-see-OH-choh"
19	diecinueve	dieci + nueve	"dyeh-see-NWEH-beh"

Tip: Note the accent mark on dieciséis — it breaks the default stress rule and is the only number in this group that requires one.

Numbers 20–29: The "Veinti-" Pattern

Numbers 20–29 follow a similar pattern, using veinti- (a contraction of veinte y). They are also written as one word.

Number	Spanish	Breakdown	Pronunciation
20	veinte	—	"BAYN-teh"
21	veintiuno	veinti + uno	"bayn-tee-OO-noh"
22	veintidós	veinti + dos	"bayn-tee-DOHS"
23	veintitrés	veinti + tres	"bayn-tee-TREHS"
24	veinticuatro	veinti + cuatro	"bayn-tee-KWAH-troh"
25	veinticinco	veinti + cinco	"bayn-tee-SEEN-koh"
26	veintiséis	veinti + seis	"bayn-tee-SAYS"
27	veintisiete	veinti + siete	"bayn-tee-SYEH-teh"
28	veintiocho	veinti + ocho	"bayn-tee-OH-choh"
29	veintinueve	veinti + nueve	"bayn-tee-NWEH-beh"

Tip: Veintidós, veintitrés, and veintiséis all have accent marks. This is because they are aguda words (stressed on the last syllable) that end in a vowel or s.

The Tens: 30, 40, 50, 60, 70, 80, 90

Number	Spanish	Pronunciation
30	treinta	"TRAYN-tah"
40	cuarenta	"kwah-REHN-tah"
50	cincuenta	"seen-KWEHN-tah"
60	sesenta	"seh-SEHN-tah"
70	setenta	"seh-TEHN-tah"
80	ochenta	"oh-CHEHN-tah"
90	noventa	"noh-BEHN-tah"

Tip: All the tens from 30 to 90 end in -enta (except treinta which ends in -einta). This pattern makes them easier to remember.

Numbers 31–99: The "Y" Pattern

From 30 onwards, compound numbers are written as three separate words, connected by y (and).

Pattern: tens + y + units

Number	Spanish	Pronunciation
31	treinta y uno	"TRAYN-tah ee OO-noh"
32	treinta y dos	"TRAYN-tah ee dohs"
33	treinta y tres	"TRAYN-tah ee trehs"
42	cuarenta y dos	"kwah-REHN-tah ee dohs"
55	cincuenta y cinco	"seen-KWEHN-tah ee SEEN-koh"
67	sesenta y siete	"seh-SEHN-tah ee SYEH-teh"
74	setenta y cuatro	"seh-TEHN-tah ee KWAH-troh"
86	ochenta y seis	"oh-CHEHN-tah ee says"
99	noventa y nueve	"noh-BEHN-tah ee NWEH-beh"

Important: Notice the difference: 16–29 are written as one word (dieciséis, veintiuno), but 31–99 are written as three words (treinta y uno, cuarenta y dos).
