Post 132/365
Es sábado, el 5 de agosto de 2017


Welcome to Spanish Blog 365 and thanks so much for stopping by.

In today’s Post we’ll learn ordinal numbers and how to abbreviate them.


Ordinal Numbers in Spanish – just as it says, we’re putting things in order.

Ordinal numbers are used much more in English then they are in Spanish.
For example:


August 5th, February 19th, etc…
Spanish uses ‘cardinal numbers’ for dates: el 5 de mayo, el 14 de febrero


Street names:
Está en la calle 136 – It’s on the Street 136
English: It’s on 136th Street



Ordinal numbers in Spanish – first thru tenth

Los números ordinales en español

primero/a  (1ro/a)         first  (1st)

segundo/a  (2do/a)      second  (2nd)

tercero/a  (3ro/a)           third  (3rd)

cuarto/a   (4to/a)         
fourth (4th)

quinto/a   (5to/a)         fifth (5th)

sexto/a   (6to/a)            sixth     (6th)

séptimo/a   (7mo/a)    seventh  (7th)

octavo/a  (8vo/a)         eigth (8th)

noveno/a  (9no/a)       ninth (9th)

décimo/a  (10mo/a)   tenth (10th)


1. Notice how séptimo, octavo, noveno y décimo look like … septiembre, octubre, noviembre, diciembre
these were the 7th, 8th, 9th and 10th month.


2. Abbreviations: In English we take the last two letters of the word to make the abbreviation. first 1st, second 2nd, etc…
In Spanish it’s the same.
Primero 1ro, segundo 2do, octavo 8vo, etc…


OJO: sometimes Spanish only uses the last letter. 1o or 1a for primero / primera or 5o or 5a for quinto / quinta


3. Primero  and tercero drop the final -o in front of a masculine noun.

el primer día
el tercer mes


4. All of these numbers have a feminine form depending on what is being described as well as a plural form.

El primer piso
La primera puerta

El tercer libro
La tercera idea

El séptimo mes
La sépitma sesión
