Adjective position and short descriptions
In Spanish the adjective usually comes after the noun. For beginners, this is the common pattern: noun + color. You will also see the adjective before the noun sometimes for poetic or emphatic effects, but start with the standard order.
Standard: La casa roja es grande. (The red house is big.)
Less common emphasis: La roja casa… (Not typical for beginners.)
Other helpful adjectives and combinations
Combine rojo and roja with simple adjectives you already know to make useful phrases.

rojo claro / roja clara (light red)
rojo brillante / roja brillante (bright red)
Example: La blusa roja oscura es elegante. (The dark red blouse is elegant.)
Common mistakes beginners make
Here are realistic errors learners often make, with corrections and short explanations.
Mistake: El camisa rojo … Correction: La camisa roja … Reason: camisa is feminine, so use la and roja.
Mistake: Las manzana rojas … Correction: Las manzanas rojas … Reason: plural noun needs plural article and adjective.
Mistake: Quiero el camisa rojo. Correction: Quiero la camisa roja. Reason: match article and gender.
Tips to avoid mistakes
Always learn the article with the noun: el libro, la mesa, la silla. If you know the noun’s gender, adding rojo or roja becomes automatic.
Practice short phrases aloud: la casa roja, el coche rojo, las flores rojas.
When in doubt, look at the article: la = feminine, el = masculine.
