What are Ordinal Numbers?
Before we dive into the specifics of "números ordinales 20", let's first understand what ordinal numbers are. Ordinal numbers are a sequence of numbers that denote the position or order of an item in a list or sequence.

Ordinal Numbers in Spanish: "Números Ordinales"
In Spanish, ordinal numbers are known as "números ordinales". They are formed by adding the suffix '-o' to the end of a cardinal number, with a few exceptions. Understanding "números ordinales 20" requires a basic understanding of how Spanish ordinal numbers work.
Forming Spanish Ordinal Numbers
- For most numbers, add '-o' to the end of the cardinal number. For example, 1o, 2o, 3o, etc.
- For numbers ending in '-o', the suffix changes to '-avo'. For example, 11o becomes 11avo.
- For numbers ending in '-a', the suffix changes to '-eno'. For example, 1a becomes 1ena.
Understanding "Números Ordinales 20"
"Números ordinales 20" refers to the 20th position in a sequence. In Spanish, "20o" is used to denote this position. However, as with many rules in language, there are exceptions. In Spanish, the ordinal number for 20 is actually "vigésimo".
Why the Exception?
The exception with "20o" is due to the Spanish language's preference for using the vigesimal system (base 20) instead of the decimal system (base 10) for ordinal numbers above 19. This is why you'll see "vigésimo" used instead of "20o".
Using "Vigésimo" in Context
Now that we understand "vigésimo" is used for the 20th position, let's look at how it's used in context. Here are a few examples:
| English | Spanish |
|---|---|
| 20th day of the month | 20 de mes |
| 20th president | vigésimo presidente |
| 20th century | siglo vigésimo |
