Usage notes[edit]

  • Most Spanish adjectives appear after the modified noun when used attributively. Forms of tercero, however, as with all ordinal numerals, can appear before the modified noun.
  • When used before a masculine singular noun, the apocopate form tercer is used instead of tercero:
Es el tercer hijo.
[He] is the third son.
Es el hijo tercero.
[He] is the third son.
  • This adjective is often used substantively, with the modified noun implied but omitted.
¿Cuál hijo es? Es el tercero.
Which son is [he]? [He] is the third [son].


tercero m (plural terceros)

  1. (law) third party
  2. mediator
