Answer:
The preterite tense of the verb "ser" (to be) in Spanish is as follows:
- Yo fui (I was)
- Tú fuiste (You were, informal singular)
- Él/Ella/Usted fue (He/She/You were, formal singular)
- Nosotros/Nosotras fuimos (We were)
- Vosotros/Vosotras fuisteis (You all were, informal plural - mainly used in Spain)
- Ellos/Ellas/Ustedes fueron (They/You all were)
The preterite tense is used to talk about actions or states of being that occurred at a specific point in the past and are viewed as completed events.
