Numbers
Basic Numbers
- The Spanish numbers 0 - 10: cero (0), uno/una (1), dos (2), tres (3), cuatro (4), cinco (5), seis (6), siete (7), ocho (8), nueve (9), diez (10).
- Spanish numbers 11 - 20: once (11), doce (12), trece (13), catorce (14), quince (15), dieciséis (16), diecisiete (17), dieciocho (18), diecinueve (19), veinte (20).
Tens
- Spanish numbers 21 - 100: Verbally combine ten (diez) with units, e.g., veintiuno (21), veintidós (22), treinta y tres (33), cuarenta y cuatro (44), cincuenta y cinco (55), sesenta y seis (66), setenta y siete (77), ochenta y ocho (88), noventa y nueve (99), cien (100).
- For number above 30, the units come after 'y' (and).
Hundreds
- Hundred in Spanish is ciento.
- From 200 - 900, combine number with hundred, e.g., doscientos (200), trescientos (300), cuatrocientos (400), quinientos (500), seiscientos (600), setecientos (700), ochocientos (800), novecientos (900).
- These can be combined with tens and units, e.g., doscientos veintiuno (221).
Thousands
- Thousand in Spanish is mil.
- To express multiple thousands, state the number and follow with 'mil', e.g., dos mil (2000), diez mil (10,000).
Larger Numbers
- Million in Spanish is millón, with multiples expressed as 'millones', e.g., dos millones (2 million).
- Billion in Spanish is mil millones or billón, depending on the country.
Important Points
- Note that in Spanish, periods and commas are used as decimal and thousands separators differently than in English: 1.234,56 in Spanish = 1,234.56 in English.
- Plurals of 'cien' and 'mil' are 'cientos' and 'miles' but only used when not followed by a specific number.
- Una is used instead of uno before a feminine noun.
- Remember Spanish numbers will agree in gender with the noun they modify.
- Non-exact numbers and quantities are often expressed using 'millares' (thousands) or 'cientos' (hundreds) in Spanish. e.g., "millares de personas" means "thousands of people".
