The preterite of hacer describes a completed past action at a specific moment. The yo form 'hice' and the él/ella/usted form 'hizo' (with a 'z', not a 'c') are the two most-asked-about forms — both irregular.

Tip

Working with the preterite

The preterite describes a finished past action with a clear boundary — "ayer comí pizza" (yesterday I ate pizza). The key contrast is with the imperfect, which describes ongoing or repeated past actions without a defined endpoint. If you can substitute "used to" or "was doing" in English, you usually want the imperfect; if the action is one-and-done, you want the preterite. The irregular preterites (fui, hice, dije, tuve, vine, supe) are the highest-frequency in Spanish — front-load them.

Questions

Frequently asked questions

How do you conjugate hacer in the preterite?
The preterite of hacer is: yo hice, tú hiciste, él/ella/usted hizo, nosotros/as hicimos, vosotros/as hicisteis, ellos/ellas/ustedes hicieron. Note that the él/ella/usted form is 'hizo' with a 'z' — the only person where the stem switches from 'hic-' to 'hiz-'.
Why is the él form 'hizo' spelled with 'z' instead of 'c'?
Spanish orthography requires 'z' before 'o' or 'a', and 'c' before 'e' or 'i' for the same sibilant sound. The preterite stem of hacer is phonetically the same for every person; before 'iste' (hiciste) it's spelled with 'c', but before 'o' (hizo) it must switch to 'z'. The sound stays the same — only the spelling changes.
Should I use 'hice' (preterite) or 'hacía' (imperfect)?
Use the preterite 'hice' for a completed action at a specific moment: 'Ayer hice ejercicio' (Yesterday I exercised). Use the imperfect 'hacía' for habitual or ongoing past actions without a clear endpoint: 'De niño, hacía ejercicio todos los días' (As a child, I used to exercise every day). The contrast is finished vs ongoing.
