tercero (feminine singular tercera, masculine plural terceros, feminine plural terceras)

1. third

• 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].
