6.1 Spanish Numbers 101 and Higher Grammar Notes

Section 6.1: Numbers 101 and Higher

Spanish numbers and their usage involve specific rules regarding punctuation, gender agreement, and terminology for large quantities.

Punctuation Rules for Large Numbers

In Spanish grammar and standard notation, a period ($.$.), rather than a comma ($,$), is used to indicate thousands and millions. This is the inverse of standard English notation.

• Example: $550.000$ (quinientos cincuenta mil)

• Example: $1.000.000$ (un mill?n)

Cardinal Numbers: 101 to 8.000.000

The following is an exhaustive list of the numbers provided in the tutorial:

• 101: ciento uno

• 128: ciento veintiocho

• 200: doscientos/as

• 300: trescientos/as

• 400: cuatrocientos/as

• 500: quinientos/as

• 600: seiscientos/as

• 700: setecientos/as

• 800: ochocientos/as

• 900: novecientos/as

• 1.000: mil

• 1.100: mil cien

• 2.000: dos mil

• 5.000: cinco mil

• 100.000: cien mil

• 200.000: doscientos mil

• 550.000: quinientos cincuenta mil

• 1.000.000: un mill?n (de)

• 8.000.000: ocho millones (de)

Gender Agreement in Numbers (200–999)

The numbers $200$ through $999$ must agree in gender with the nouns they modify. This means the ending changes from -os to -as depending on whether the noun is masculine or feminine.

• 324 tiendas: trescientas veinticuatro tiendas (feminine)

• 873 habitaciones: ochocientas setenta y tres habitaciones (feminine)

• 500 mujeres: quinientas mujeres (feminine)

• 605 clientes: seiscientos cinco clientes (masculine)

• 990 euros: novecientos noventa euros (masculine)

• 257 estudiantes: doscientos cincuenta y siete estudiantes (masculine)

Specific Usage Rules (Observations)

Usage of 101

There is a distinction in the form of the number $101$ based on its function in a sentence:

• Ciento uno: Used strictly for counting (e.g., cien, ciento uno, ciento dos…).

• Ciento un(a): Used when describing a specific quantity of nouns.

  • Example: ciento una noches (one hundred and one nights).

Terminology for Billion and Trillion

There is a significant difference between Spanish and English terms for very large numbers, which can lead to confusion:

• Billion ($1.000.000.000$): Expressed as mil millones in Spanish.

  • Example: Hay mil millones de personas en China (There are a billion people in China).

• Trillion ($1.000.000.000.000$): Expressed as un bill?n in Spanish.

  • Example: Hay un bill?n de planetas en el universo (There are a trillion planets in the universe).

Mil and Mill?nes

• Mil: This can mean either "thousand" or "one thousand." It does not change whether the noun is plural or singular.

  • Example: $1.000$ d?lares = mil d?lares

  • Example: $5.000$ bicicletas = cinco mil bicicletas

• Mill?n: The term for a million or one million. The plural form is millones, which notably loses the accent mark over the "o."

  • Example: $1.000.000$ de personas = un mill?n de personas

  • Example: $2.000.000$ de pesos = dos millones de pesos

Grammatical Construction with "de"

When the words mill?n or millones are used directly before a noun, the preposition de must be placed between the number and the noun.

• $1.000.000$ de hombres = un mill?n de hombres

• $12.000.000$ de aviones = doce millones de aviones

• $15.000.000$ de personas = quince millones de personas

Expressing Years in Spanish

Unlike English, where years are often expressed as pairs of two-digit numbers (e.g., nineteen seventy-nine for $1979$), Spanish expresses years as a single full number.

• 1945: mil novecientos cuarenta y cinco

• 1898: mil ochocientos noventa y ocho

• 2015: dos mil quince

• 1220: mil doscientos veinte
