📖 Clase (60 min)
Introducción y contexto
Ayer aprendiste a afirmar en pasado con was/were. Hoy aprendes lo contrario: a negar. Negar es tan importante como afirmar, porque la vida real está llena de "no estaba ahí", "no era así", "no fue mi culpa", "no había nadie". La buena noticia es que negar el pasado de to be es muy fácil: solo añades not después del verbo. No necesitas verbos auxiliares como didn't (eso vendrá con otros verbos más adelante). El verbo to be se niega solo, igual que en presente (I'm not, she isn't).
Explicación detallada (regla por regla)
1. La regla básica: was/were + not.
Sujeto + was/were + not + (complemento)
- I was not at home. → No estaba en casa.
- They were not happy. → No estaban contentos.
2. Contracciones (lo natural al hablar).
| Forma larga | Contracción | Ejemplo |
|---|---|---|
| was not | wasn't | He wasn't there. (No estaba ahí.) |
| were not | weren't | We weren't ready. (No estábamos listos.) |
Las contracciones wasn't y weren't son las que usarás casi siempre al hablar. La forma larga (was not) suena más enfática o formal.
3. Tabla completa de la negación:
| Pronombre | Negativo largo | Contracción |
|---|---|---|
| I | I was not | I wasn't |
| You | You were not | You weren't |
| He/She/It | He was not | He wasn't |
| We | We were not | We weren't |
| They | They were not | They weren't |
4. Negar la existencia: there wasn't / there weren't = "no había".
- There wasn't any milk. → No había leche. (singular/incontable)
- There weren't any people. → No había gente. (plural)
- There wasn't a problem. → No había ningún problema.
Fíjate en any: en frases negativas usamos any, no some. ✗ There wasn't some milk. → ✓ There wasn't any milk.
5. Uso típico: corregir o contrastar.
- It wasn't my fault. (No fue culpa mía.)
- The hotel wasn't expensive; it was cheap. (El hotel no era caro; era barato.)
- We weren't at the party. We were at home. (No estábamos en la fiesta. Estábamos en casa.)
Vocabulario clave

Gramática a fondo
Posición de not: siempre inmediatamente después de was/were.
- ✓ She was not tired. / She wasn't tired.
- ✗ She not was tired. / ✗ She didn't was tired.
No uses didn't con to be. Esto es un error muy frecuente. to be se niega solo:
- ✗ I didn't was at home. → ✓ I wasn't at home.
- ✗ They didn't were happy. → ✓ They weren't happy.
Negar edad / nacimiento:
- He wasn't 18 then; he was 16. (No tenía 18 entonces; tenía 16.)
- She wasn't born in Spain; she was born in France. (No nació en España; nació en Francia.)
Doble información (no… sino): en inglés se usa not… but:
- It wasn't boring, but interesting. → No era aburrido, sino interesante.
Pronunciación y notas de uso
- wasn't → "UÓ-sent", la t final apenas se oye en habla rápida.
- weren't → "UÉR-ent", una sola sílaba marcada; cuidado de no decir "uéren".
- En conversación natural, la contracción es casi obligatoria. I was not suena enfático: "I WAS NOT there!" (¡Que NO estaba ahí!).
- wasn't vs weren't: el error típico es decir weren't con I/he/she. Recuerda: I/he/she/it → wasn't.
Errores comunes del hispanohablante
- ✗ I didn't was at home. → ✓ I wasn't at home.
- ✗ They didn't were ready. → ✓ They weren't ready.
- ✗ She no was happy. → ✓ She wasn't happy.
- ✗ He weren't there. → ✓ He wasn't there.
- ✗ There wasn't some money. → ✓ There wasn't any money.
- ✗ We not were tired. → ✓ We weren't tired.
- ✗ It wasn't no my fault. (doble negación) → ✓ It wasn't my fault.
