Since
ordinal numbers change in gender and number, let's see
how does it look like:
 |
el primer hombre= the first man
|
 |
la primera mujer = the first woman / wife |
 |
los primeros hombres= the first men |
 |
las primeras mujeres= the first women / wives |
 |
el segundo libro= the second book |
 |
la segunda casa= the second house |
 |
los quintos pisos= the fifth floors |
 |
los terceros países= the third world countries |
 |
los cuartos cursos= the fourth classes |
 |
la segunda mujer= the second woman / wife |
 |
el segundo hombre= the second man |
 |
la cuarta mujer= the fourth woman / wife |
 |
de la cuarta mujer= of the fourth woman / wife |
 |
a la cuarta mujer= to the fourth woman / wife |
 |
por la cuarta mujer= because of the fourth woman / wife |
 |
el cuarto hombre= the fourth man |
The formation of the ordinal numbers is shown in principle
with the following little table. A complete overview
you'll find in chapter
18.2.2. As you can see a higher ordinal number is
formed by creating the ordinal number of every element
of this figure.
