Cardinal Numbers: Basic Rules
Writing and Pronouncing Numbers
In Spanish, cardinal numbers (uno, dos, tres, etc.) are used to count and quantify. Numbers from zero to thirty are typically written as a single word, while numbers from thirty-one onwards are written in parts, connected by y (and). For example:
- 16: dieciséis
- 23: veintitrés
- 31: treinta y uno
- 45: cuarenta y cinco
Gender Agreement
Numbers like uno and those ending with uno (veintiuno, treinta y uno) change according to gender and placement:
- Before a masculine noun: uno becomes un (un libro – one book)
- Before a feminine noun: uno becomes una (una casa – one house)
- Veintiún estudiantes (21 students, masculine), veintiuna casas (21 houses, feminine)
Numbers and Plurality
Numbers from 200 onward agree in gender with the noun:
- Doscientos libros (200 books)
- Doscientas sillas (200 chairs)
Ordinal Numbers: Order and Placement
Ordinal numbers (primero, segundo, tercero, etc.) are used to indicate order. They also agree in gender and number with the noun they describe:
- El primer día (The first day)
- La segunda semana (The second week)
- El tercer capítulo (The third chapter)
Note: Primero and tercero drop the final -o before a singular masculine noun.
Writing Large Numbers
In Spanish, periods and commas are used differently from English. A period separates thousands, and a comma is used for decimals:
- 1.000 (one thousand)
- 1.000.000 (one million)
- 2,5 (two point five)
Spanish does not use and between hundreds and tens (e.g., ciento veinte not ciento y veinte).
Expressing Dates in Spanish
Date Order
Dates in Spanish follow a day-month-year format, unlike the month-day-year format common in the US. For example:
- 10/06/2024 (June 10th, 2024) in Spanish: 10 de junio de 2024
Writing and Saying Dates
Use the following structure for dates:
- El + day + de + month + de + year
- El 15 de marzo de 2023
For the first day of the month, use primero instead of uno:
- El primero de mayo (May 1st)
Days of the Week and Months
Days of the week and months are not capitalized in Spanish:
- lunes, martes, miércoles (Monday, Tuesday, Wednesday)
- enero, febrero, marzo (January, February, March)
Abbreviations and Common Mistakes
Common abbreviations for days and months include:
- lun. (lunes), mar. (martes), mié. (miércoles)
- ene. (enero), feb. (febrero), mar. (marzo)
Avoid translating English date formats directly. Remember to always use the Spanish day-month-year order and lowercase for days and months.
