Numbers from 16 to 30

2. Numbers from 16 to 30 Rule #1; Numbers zero to 30 are one word. No spaces in between, no using ‘y” (and). Rule #2: Numbers 16 to 19 are formed by using the root Dieci (means 10) and the unit number: e.g. 17= diecisiete. Do not use “y” (and) to put together the two words to form the number. Rule #3: Numbers 21 to 29 are formed by using the root veinti (means 20) and the unit number. e.g. 29= veintinueve. Do not use “y” (and) to put together the two words to form the number.

Rule #2: The roots of the ten place number multiples of ten do not change when adding a unit. E.g. #40= Cuarenta and #41 = Cuarenta y uno. This rules applies to numbers less than 100.

10. Enrichment information • Thousands and decimals. Traditionally, in Spanish either dots or commas are used to separate the thousands. It depends on the country. But, more recently (and precisely to avoid confusion) a blank space is recommended instead, and a comma is recommended for decimals. So 22,500.99 would be 22 500,99. • Years in Spanish. To name a year, simply say its number. So, 1975 would not be nineteen seventy five, but “simply” one thousand nine hundred and seventy five (mil novecientossetenta y cinco).

11. Enrichment information • Gender in Spanish numbers. Note that some Spanish numbers must follow the gender, when they qualify a noun. For example to say 21 tables, in Spanish you need to look at the genter of the noun table which is feminine, thus you would say veintiuna mesas. • Numbers as nouns. As nouns, the Spanish numbers are always masculine (el cero, el uno, el cuatro mil…) • Old-fashioned Spanish numbers. Sometimes you will read complex numerals such as diez y seis or veinte y uno (instead of dieciséis and veintiuno). This is considered old-fashioned and should be avoided.
