Preterite vs. Imperfect
Preterite vs. Imperfect
Now that you know both past tenses, the real skill is choosing between them — a decision English speakers never have to make, since English only offers one simple past.

Foreground action vs. background scene
Estaba en casa cuando sonó el teléfono. (I was at home [imperfect, background] when the phone rang [preterite, the event])
I was at home when the phone rang — one past tense handles both halves
A classic pattern: the imperfect sets the scene (what was already going on), and the preterite interrupts it with a specific completed event. English uses the exact same 'was doing X when Y happened' sentence shape, but both verbs sit in the same simple past tense — Spanish is the one splitting that single English tense into two distinct forms.
The same verb can mean something different in each tense
sabía (I knew, ongoing state) vs. supe (I found out, the moment of learning) — same verb, saber, different meaning by tense
I knew vs. I found out — English needs two different verbs to make this distinction
A handful of Spanish verbs — saber, conocer, poder, querer — shift meaning depending on which past tense they're in, because the tense itself marks whether something was an ongoing state or a single completed moment. English has to reach for entirely different verbs to capture the same distinction, which is a hint for how deliberately you'll need to choose between preterite and imperfect with these verbs specifically.
