Ordinal numbers are essential for lists: they denote the rank, position, or order of items in a group, whether that group is made up of people, objects, or things to do.

Spanish ordinal numbers

first   primero
second   segundo 2nd
third   tercero
fourth   cuarto 4th
fifth   quinto 5th
sixth   sexto 6th
seventh    séptimo 7th
eighth   octavo 8th
ninth   noveno 9th
tenth   décimo 10th  10º


When primero and tercero precede a masculine noun, they change to the short-form adjectives primer and tercer.

Por ejemplo…

José está en segundo lugar y Alberto está en quinto.   José is in second place and Alberto is in fifth.
En primer lugar, tenemos que elegir un presidente.   In the first place, The first thing we need to do is choose a chairperson.

All Spanish ordinal numbers have feminine forms – just change the o to a: la segunda , la séptima

The ordinal numbers up to tenth usually precede the noun. After tenth, however, ordinal numbers are commonly expressed with just the cardinal number after the noun:

el segundo piso   the second floor
el piso veinte   the twentieth floor

 Most ordinal numbers are identical to their corresponding fractions.

 If you have trouble remembering the difference between ordinal and cardinal numbers, try this mnemonic:

  • ordinals are for ordering
  • cardinals are for counting cards
