Subject-Verb Agreement (Concordancia Sujeto-Verbo)
¿Qué es Subject-Verb Agreement?
La concordancia sujeto-verbo es la regla que dice que el verbo debe coincidir con el sujeto en número (singular o plural) y persona (1ª, 2ª, 3ª).
Regla básica:
Singular Subject = Singular Verb
He works every day.
She likes coffee.
The cat sleeps on the bed.
Plural Subject = Plural Verb
They work every day.
We like coffee.
The cats sleep on the bed.
Errores comunes:
| ❌ INCORRECTO | ✅ CORRECTO |
|---|---|
| He go to school | He goes to school |
| They walks in the park | They walk in the park |
| She have two brothers | She has two brothers |
| The students is here | The students are here |
Casos especiales:
1. Sujetos compuestos con AND
Generalmente van con verbo plural:
Tom and Mary are students. (plural)
2. "Each" y "Every"
Siempre van con verbo singular:
Each student has a book.
Every child likes ice cream.
3. Sustantivos colectivos
Pueden ser singular o plural (varía según la región):
The team is ready. (singular - enfoque en la unidad)
The team are ready. (plural - enfoque en los individuos)
Tabla de referencia rápida:
| Pronombre / Sujeto | Verbo (Present Simple) | Ejemplo |
|---|---|---|
| I | am / do / like | I like books |
| You | are / do / like | You like books |
| He/She/It | is / does / likes | He likes books |
| We | are / do / like | We like books |
| They | are / do / like | They like books |
⚡ Tips importantes:
- En tercera persona singular (he, she, it), el verbo en presente simple lleva -s o -es
- Con "does" y "doesn't", el verbo principal NO lleva -s
- Ejemplo: He does like (NO: does likes)
- En exámenes como IELTS y TOEFL, este es uno de los errores más comunes
