The ordinals for first and third have shorter forms in a particular position.

The idea

Before a masculine singular noun, use primer and tercer: el primer día, el tercer piso. Feminine nouns use primera and tercera. When used without a following noun, use the full form: el primero, el tercero.

Examples

  • Hoy es mi primer día.Today is my first day.
  • Vivo en el tercer piso.I live on the third floor.
  • Es la primera vez aquí.It is the first time here.
  • La tercera clase empieza pronto.The third class starts soon.
  • Mi primer libro está allí.My first book is over there.
  • El tercero espera en la fila.The third person is waiting in line.

Watch out

When the noun follows, standard formal usage prefers primera for a feminine noun; shortened primer is heard in some American varieties.
