The number “one” changes from “uno” to “un” before a masculine noun:

un carro = one car (or a car)

un perro = one dog (or a dog)

un hombre = one man (or a man)

The number “one” changes from “uno” to “una” before a feminine noun:

una pluma = one pen (or a pen)

una gata = one cat (or a cat ((female))

una chica = one/a girl

When counting generically (one, two, three …) use “uno” but when counting specifically (one cat, one dog), use “un” or “una.”
