Learn how to avoid Spanish gender and agreement mistakes with nouns, articles and adjectives.
Spanish nouns have gender, and articles and adjectives usually agree with the noun in gender and number.
Incorrect vs correct Spanish
Use the corrected version as a model sentence. The explanation tells you what pattern to remember.
| Incorrect | Correct | Why it changes |
|---|---|---|
| el casa bonito | la casa bonita | Casa is feminine, so article and adjective agree. |
| la problema importante | el problema importante | Problema is masculine despite ending in -a. |
| los persona | las personas | Persona is feminine. |
| una día buena | un buen día | Día is masculine and bueno becomes buen before it. |
| mis amigo | mis amigos | Plural nouns need plural agreement. |
| la agua fría | el agua fría | Agua uses el in singular but the adjective is feminine. |
Correction strategy
Do not try to fix every sentence at once. Choose one repeated mistake, learn two correct examples, and reuse them until they feel automatic.
Fix and repeat
Say three sentences aloud using one Spanish expression from this page. Then replace one word to make the sentence personal.
- Read the Spanish example slowly.
- Repeat it without looking at the English meaning.
- Change the person, time or place.
