Masculine and feminine numbers

In Spanish, all numbers ending in one have both a masculine and a feminine form.

  • Uno is used to replace a known, masculine, singular quantity that has already been referenced in the conversation.
  • Tengo diez melones. ¿Quiere uno grande?
    I have ten melons. Do you want a big melon?

  • Un is used in front of masculine and singular nouns.
  • No, quiero un melón pequeño
    No, I want a small melon

  • Una is used in front of feminine and singular nouns.
  • También tengo una sandía.
    Also, I have a watermelon.

    No gracias, ya tengo una
    No thanks, I have a watermelon

In Spanish, the number "one" is used like the article "a/an".
