English speakers usually learn a simple rule for Spanish adjectives: they go after the noun. While putting them before the noun is sometimes just a stylistic or poetic choice, there is a specific group of adjectives where the position completely changes the message.
For these special words, moving the adjective is not about sounding fancy. Words like viejo, pobre, and nuevo tell an entirely different story depending on whether they sit in front of the noun or behind it.

Literal versus figurative
As a general rule, an adjective placed after the noun carries its literal, objective, or physical meaning. When placed before the noun, the same adjective takes on a figurative, subjective, or abstract meaning.
Take pobre, for instance. After the noun, it means someone literally has no money. Before the noun, it means they are unfortunate.
Ese hombre pobre no tiene casa.
(That poor man does not have a house.)
Mi pobre amigo perdió su trabajo.
(My unfortunate friend lost his job.)
The word viejo works similarly. After the noun, it means physically old or elderly. Before the noun, it refers to a longstanding relationship.
Ayer visité a una amiga vieja.
(Yesterday I visited an elderly friend.)
Ayer visité a una vieja amiga.
(Yesterday I visited a longstanding friend.)
Everyday objects and people
You will see this shift with many common adjectives describing everyday things and people. The word grande means big in size after the noun, but drops its final syllable to become gran before a singular noun to mean great or outstanding.
Es un hombre grande.
(He is a large man.)
Es un gran hombre.
(He is a great man.)
The word nuevo means brand new after the noun. When placed before, it simply means newly acquired or another one. Likewise, alto changes from physical height to high rank, and antiguo changes from ancient to former.
Compré un coche nuevo.
(I bought a brand-new car.)
Este es mi nuevo coche.
(This is my new car.)
Hablamos con un alto funcionario.
(We spoke with a high-ranking official.)
Truth, uniqueness, and numbers
Other adjectives act more like words that identify or count things when placed before the noun. For example, único means unique after the noun, but only before it. The word cierto means true after the noun, but a certain or specific before it. Even solo changes from lonely to single.
Fue una oportunidad única.
(It was a unique opportunity.)
Es el único problema.
(It is the only problem.)
No es una historia cierta.
(It is not a true story.)
Tengo una cierta edad.
(I am of a certain age.)
Lo construyó un solo hombre.
(A single man built it.)
Summary
When in doubt, remember that placing these adjectives after the noun highlights literal, physical traits. Placing them before the noun highlights abstract, emotional, or figurative qualities.
