Tengo un coche rojo y una casa grande.I have a red car and a big house.

English puts the adjective in front of the noun: a red car. Spanish usually does the opposite: a descriptive adjective normally follows the noun, while a small group of words (quantities, numbers, a few adjectives with short forms) come before it.

Quick shortcut: an adjective that describes (color, size, nationality, personality) goes after the noun: un coche rojo. A word that counts or orders (mucho, dos, primero) goes before it: muchos amigos. Five common adjectives shorten before a singular noun: buen, mal, primer, tercer, gran.

Descriptive adjectives follow the noun

Adjectives that tell you what something is like (its color, shape, size, nationality or personality) normally come right after the noun:

  • un coche rojo (a red car)
  • una casa grande (a big house)
  • un libro interesante (an interesting book)
  • una chica española (a Spanish girl)
  • los estudiantes simpáticos (the friendly students)

The usual agreement rules still apply: un coche rojo, una casa roja, los coches rojos.

With two adjectives, both usually go after the noun, joined by y: un chico alto y simpático (a tall, friendly boy).

Putting a descriptive adjective before the noun is possible too, but it's a different, more expressive or literary choice (una hermosa casa, "a beautiful house"). For everyday, neutral description, after the noun is the pattern to reach for.

Quantity words and numbers come before the noun

Words that say how many or how much go before the noun, along with numbers:

  • muchos amigos (many friends)
  • pocas horas (few hours)
  • tres gatos (three cats)
  • otro café (another coffee)

Mucho and poco agree with the noun like any other adjective (mucha gente, muchos libros, pocas horas). Otro already means "another," so it isn't combined with un/una: otro café, not un otro café.

Ordinals (primero, segundo, tercero…) also come before the noun: la segunda casa (the second house), el tercer día (the third day).

Possessive adjectives (mi casa) and demonstrative adjectives (este libro) come before the noun as well; each has its own lesson.

Five common adjectives that shorten before a singular noun

Some very common adjectives lose their final -o (and grande loses -de) when they come right before a singular noun. These five are the ones to know first; a few other words (like alguno → algún) shorten in a similar way:

Full form Short form Example
bueno buen un buen amigo (a good friend)
malo mal un mal día (a bad day)
primero primer el primer día (the first day)
tercero tercer el tercer piso (the third floor)
grande gran un gran amigo, una gran amiga (a great friend, an important friend)

Two details to notice:

  • Buen, mal, primer and tercer shorten only before a masculine singular noun. A feminine noun keeps the full form: una buena amiga, la primera vez, la tercera casa. The plural keeps it too: buenos amigos.
  • Gran shortens before a singular noun of either gender (un gran día, una gran idea). In the plural it goes back to grandes: grandes amigos.

The short form appears only right before the noun. Once an adjective follows the noun, it keeps its full form: una casa grande.

gran and grande mean different things

Position often shifts the meaning here: before the noun, gran tends to stress importance or distinction ("great, notable"), while grande after the noun usually means large in size or extent. Context decides the exact shade:

  • un gran hombre (a great man) vs. un hombre grande (a big man)
  • una gran ciudad (a great, important city) vs. una ciudad grande (a large city)

Common mistakes

  • un bueno amigo → ✅ un buen amigo (bueno shortens before a masculine singular noun)
  • una buen amiga → ✅ una buena amiga (a feminine noun keeps the full form)
  • un grande día → ✅ un gran día (grande shortens before a singular noun)
  • amigos muchos → ✅ muchos amigos (quantity words go before the noun)
  • un otro café → ✅ otro café (otro already means "another," so it drops un)

Key takeaways

  • Descriptive adjectives (color, size, nationality, personality) normally follow the noun: un coche rojo, una casa grande.
  • Quantity words, numbers and ordinals come before the noun: muchos amigos, tres gatos, el segundo día.
  • Bueno, malo, primero and tercero shorten to buen, mal, primer, tercer before a masculine singular noun; grande shortens to gran before any singular noun.
  • The short forms appear only directly before the noun. Feminine and plural forms stay full, and so does any adjective placed after the noun.
  • Gran before a noun often stresses importance ("great, notable"); grande after a noun usually means large in size.
  • Whatever its position, the usual agreement rules still apply to the adjective.
