Spanish Past Tenses: Preterite vs. Imperfect – Complete Study Notes

Overview of Spanish Past Tenses

  • Spanish has two main simple past tenses that learners often confuse:

    • Pretérito (Preterite)

    • Imperfecto (Imperfect)

  • Understanding the difference is key to accurate storytelling and description in Spanish.

    • Preterite = “snapshot” of a finished event

    • Imperfect = “moving picture” that shows ongoing, habitual, or background actions.


Pretérito (Preterite) – The “Snapshot” Tense

  • Core Idea: Describes completed actions that occurred once or at a specific point in time and are now finished.

  • Time-frame clarity: Action has a definite beginning and end, even if the exact time markers aren’t stated.

  • Metaphor: Think of a single photo capturing a moment in the past.

  • Examples from the lesson:

    • “Yesterday, I went to the movies.”

    • Indicates a one-time, finished action.

    • “Yesterday, I studied for 2 hours.”

    • Specifies a fixed duration (start and finish understood).

  • Typical triggers/keywords (implied from context): ayer, anoche, la semana pasada, el año pasado, etc.


Imperfecto (Imperfect) – The “Moving Picture” Tense

  • Core Idea: Describes ongoing, habitual, or repetitive actions in the past without a clear endpoint.

  • Scene-setting: Provides background details, descriptions, or context for a story.

  • Metaphor: A film reel that shows action unfolding over an undefined stretch of time.

  • Examples from the lesson:

    • “When I was a child, I used to play in the park.”

    • Highlights a habit (repeated activity in childhood). No precise start/end.

    • “At university, I studied a lot.”

    • Implies a long-term habit during the university years, not a single session.

  • Typical triggers/keywords (implied): mientras, siempre, a menudo, todos los días, de niño/a, etc.

Combining the Two Tenses in One Narrative

  • Technique: Use Imperfect to set the scene ➔ switch to Preterite for specific one-time events.

  • Example from the video:

    1. Imperfect scene-setting: “I was at the mall …”

    2. Preterite event: “… and I ran into my cousin.”

  • Visualize a background canvas (imperfect) with bright single brush strokes (preterite) over it.


Practical Decision Checklist

  1. Is the past action complete with a known start & end?

    • YES → Use Preterite.

  2. Is it a habit, description, or ongoing background?

    • YES → Use Imperfect.

  3. Telling a story?

    • Start with Imperfect for context, then insert Preterite for each concrete event.


Real-World Application & Study Advice

  • Storytelling: Accurate tense choice makes narratives vivid and clear.

  • Pairing with Time Expressions helps reinforce the correct tense.

  • Practice Tip: Write mini-stories mixing both tenses to solidify usage.

  • Further Learning: The speaker recommends visiting the blog (links in the original video description) for “full lessons” and deeper examples.


Ethical & Pedagogical Context

  • Using clear examples (e.g., childhood habits vs. one-time events) supports ethical teaching by emphasizing comprehension over rote memorization.

  • Encouraging learners to immerse via unlimited one-on-one classes with native speakers (as advertised) promotes authentic language exposure.
