Question

What are the Spanish ordinal numbers?​

Answer 1

Answer:

When we use natural numbers for the purpose of counting and ordering elements, we call them ordinal numbers.

Explanation:

Ordinal numbers are adjectives, and part of natural numbers, which allow us to express the order or position that an element occupies. In short, they are the words we use to say what position an element takes in an ordered series.

To give a quick and understandable example:

In a 100m Olympic race, the runners reach the finish line in one position. The one who wins the gold medal has come first, the one who wins the silver medal has come second and the one with the broce medal is the third and so on.    

Answer 2

Answer:

From 1st to 10th

1st -> Primero

2nd -> Segundo

3rd -> Tercero

4th -> Cuarto

5th -> Quinto

6th -> Sexto

7th -> Séptimo

8th -> Octavo

9th -> Noveno

10th -> Décimo

From 10th to 19th

Rule: decimo+ordinals (1-10)

For example:

11th -> Décimoprimero /Décimo primero or Undécimo (another valid way to say it)

12th -> Décimosegundo / Décimo segundo

13th -> Décimotercero / Décimo tercero

However 18th-> Décimoctavo / Décimo octavo not "Décimooctavo"

and so on...

From 20th to 90th

20th -> vigésimo

• 21st -> vigésimo primero
• 22nd -> vigésimo segundo
• and so on...

30th -> trigésimo

• 31st -> trigésimo primero
• 32nd -> trigésimo segundo
• and so on... (including the following ones)

40th -> cuadragésimo

50th -> quincuagésimo (that's hard to pronunce, even for me haha)

60th -> sexagésimo

70th -> septuagésimo

80th -> octogésimo

90th -> nonagésimo

100th

100th -> centésimo

200th to 900th

Rather rare. Instead of saying the theoretically correct form, Spanish speakers in informal speech use a shortcut, instead of saying El ciclista fue el ducentésimo. (The cyclist was the 200th), it is common to hear El ciclista quedó en el lugar [número] doscientos (200). (The cyclist "got" the place [number] 200). "Doscientos" is the cardinal 200.

1,000th

1,000th -> Milésimo
