Hacer is sometimes lumped together with the totally irregular verbs because of a spelling change in the 3rd person singular.

Hacer in the preterite usually means did/made but you should check out the dozens of other uses of hacer on SpanishDict.com.

Yo hice , Tú hiciste

Ella hizo *if we leave the C there, the CO says KO instead of SO, so we change the C to a Z to keep the sound.

Nosotros hicimos, Ellos hicieron

Preterite Interrupts Imperfect

This image first shows that sometimes an action is already happening when an event interrupts, putting an end to what was happening. The action that was happening is imperfect, and the event that interrupted is preterite.

Yo estaba corriendo y me caí. I was running and I fell. (The fall interrupted the running)

Siempre gritaba, pero un día perdió su voz. He always yelled, but one day, he lost his voice.

Estábamos durmiendo cuando la alarma sonó, despertándonos. We were sleeping when the alarm rang, waking us.

Preterite occurs during Imperfect

The second image shows an ongoing imperfect action (it was hot) and the dot shows a preterite event that happened somewhere in the middle. The imperfect action SURROUNDED the preterite action. It was happening before the event and continued to happen after the event.

La sopa estaba caliente, y me quemé la lengua. The soup was hot, and I burned my tongue.

Llovía recio cuando escuché el sonido de un gatito. It was raining hard when I heard the sound of a kitten.
