Cardinals, ordinals, prices, phones, dates — complete A0 reference
Spanish numbers look intimidating but follow clear patterns . Learn 0–15 by heart (they are unique), then tens , then how to combine with y (and). After that, hundreds and thousands are predictable.
In Spain, large numbers use a full stop as thousands separator: 1.234 = mil doscientos treinta y cuatro. Decimals use a comma : 3,50 € .
| # | Spanish | # | Spanish |
|---|---|---|---|
| 0 | cero | 8 | ocho |
| 1 | uno / una* | 9 | nueve |
| 2 | dos | 10 | diez |
| 3 | tres | 11 | once |
| 4 | cuatro | 12 | doce |
| 5 | cinco | 13 | trece |
| 6 | seis | 14 | catorce |
| 7 | siete | 15 | quince |
Say these out loud until they feel automatic. Notice how 16–19 fuse dieci- with the unit, and 21 becomes veintiuno (not veinte y uno ).

| 1 | uno | 11 | once |
| 2 | dos | 12 | doce |

| 8 | ocho | 18 | dieciocho |
| 9 | nueve | 19 | diecinueve |
| 10 | diez | 20 | veinte |
Pattern: dieci- + unit (written as one word, accent on the i in 16 and 17).
16 = dieciséis · 17 = diecisiete · 18 = dieciocho · 19 = diecinueve
| Tens | Spanish | Pattern for + unit |
|---|---|---|
| 20 | veinte | veinti- + unit (21 = veintiuno, 22 = veintidós…) |
| 30 | treinta | treinta **y** cinco |
| 40 | cuarenta | cuarenta **y** ocho |
| 50 | cincuenta | … |
| 60 | sesenta | … |
| 70 | setenta | … |
| 80 | ochenta | … |
| 90 | noventa | noventa y nueve = 99 |
| Number | Spanish | Rule |
|---|---|---|
| 100 | cien / ciento | cien alone; ciento + rest (101 = ciento uno) |
| 200 | doscientos/as | Agrees with noun: doscientas personas |
| 300 | trescientos/as | … |
| 400 | cuatrocientos/as | … |
| 500 | quinientos/as | Irregular stem |
| 600 | seiscientos/as | … |
| 700 | setecientos/as | … |
| 800 | ochocientos/as | … |
| 900 | novecientos/as | … |
| 1.000 | mil | Never *un mil* — just mil |
| 2.000 | dos mil | … |
| 1.000.000 | un millón (de…) | Millón takes de: un millón de euros |
Ordinals agree in gender with the noun. They usually go before the noun (like English). Learn 1st–10th, then the pattern -avo/-ava works for most higher numbers.
| # | Masc. | Fem. | English |
|---|---|---|---|
| 1 | primero / primer* | primera | first |
| 2 | segundo | segunda | second |
| 3 | tercero / tercer* | tercera | third |
| 4 | cuarto | cuarta | fourth |
| 5 | quinto | quinta | fifth |
| 6 | sexto | sexta | sixth |
| 7 | séptimo | séptima | seventh |
| 8 | octavo | octava | eighth |
| 9 | noveno | novena | ninth |
| 10 | décimo | décima | tenth |
From 11 onward, ordinals are mostly regular -avo/-ava forms. In Spain you will hear both undécimo and decimoprimero for 11th; duodécimo and decimosegundo for 12th. Everyday speech favours the shorter forms.
| # | Masc. | Fem. | Notes |
|---|---|---|---|
| 11 | undécimo / decimoprimero | undécima / decimoprimera | Both correct in Spain |
| 12 | duodécimo / decimosegundo | duodécima / decimosegunda | Both correct in Spain |
| 13 | decimotercero / decimotercer* | decimotercera | Short form before noun: decimotercer |
| 14 | decimocuarto | decimocuarta | … |
| 15 | decimoquinto | decimoquinta | … |
| 16 | decimosexto | decimosexta | … |
| 17 | decimoséptimo | decimoséptima | … |
| 18 | decimoctavo | decimoctava | … |
| 19 | decimonoveno | decimonovena | … |
| 20 | vigésimo | vigésima | From *veinte*, not *decimo-* |
Higher ordinals are less common in speech (people often say el piso treinta ), but you will see them in writing, rankings, and formal texts. They agree in gender: trigésimo / trigésima .
| # | Masc. | Fem. |
|---|---|---|
| 30 | trigésimo | trigésima |
| 40 | cuadragésimo | cuadragésima |
| 50 | quincuagésimo | quincuagésima |
| 60 | sexagésimo | sexagésima |
| 70 | septuagésimo | septuagésima |
| 80 | octogésimo | octogésima |
| 90 | nonagésimo | nonagésima |
| 100 | centésimo | centésima |
| 200 | ducentésimo | ducentésima |

Spain uses the euro (€) . Say: Cuesta + number + euros (and céntimos if needed).
3,50 € → tres euros con cincuenta céntimos · or colloquially: tres cincuenta
1,99 € → un euro con noventa y nueve · or casi dos euros
Phone numbers : read digit by digit or in pairs — both are common in Spain.
654 32 10 08 → seis cinco cuatro, treinta y dos, diez, ocho
912 345 678 → nueve uno dos, tres cuatro cinco, seis siete ocho
Years : mil novecientos noventa (1990) · dos mil veinticuatro (2024) · mil ochocientos cincuenta (1850).
Age : Tengo + number + años .
One mixed drill: cardinals (1–1000) and ordinals (1st–20th, with gender). Say it aloud, reveal, next.
