Preterite Ser Core Usage
Describing Permanent or Inherent Traits
Use ser in the preterite to talk about essential characteristics that someone had at a specific past moment. These are not fleeting states but stable qualities such as personality, nationality, or role.
Origin, Occupation, and Time
With origin, you narrate where someone came from in a completed past event. Occupation and time frame in a finished past context also call for ser, even though in English you might say was or were.
Preterite Ir Core Usage
Completed Movement to a Place
Use ir in the preterite to express that someone physically went to a place and the action has a clear endpoint. This includes travel by any means and arrival at a destination.
Single Trips and Past Intentions
When you describe one journey in the past or an intended plan that was carried out, ir captures the motion and the completion of the trip at a specific time.
Differentiating Ser and Ir in the Preterite
Clues from Context and Time Expressions
Context is the main tool for telling ser and ir apart when forms are identical. Words like ayer, la semana pasada, or el lunes pasado strongly suggest the preterite and help you decide which verb fits the meaning.
Practical Examples and Translation Tips
Fui al mercado means went to the market, while fui médico means was a doctor. Paying attention to the noun or adjective that follows the verb guides you to choose between motion and identity, even when the surface form is the same.
