Oler Preterite Tense Conjugation in Spanish
The preterite tense of oler — "to smell" in English — is the form you need for completed actions in the past, things that happened once and ended. This page gives you the full preterite conjugation table for oler with all six persons, explains exactly how the tense is formed for this verb, shows when to use it with real examples, and finishes with a quiz so you can test yourself. Oler means "to smell" — both to notice a smell (huele bien, it smells good) and to smell something on purpose (huele la flor, smell the flower). It is an -ir stem-changing verb with a special twist: the o becomes ue in yo, tú, él and ellos, and because the word starts with a vowel, an h is added (huelo, hueles, huele, huelen) so the word does not start with ue. The preterite, which this page covers, is simpler: the stem change disappears and the forms are regular (olí, oliste, olió, olimos, olisteis, olieron), with the accent on the ó in the third person singular. Oler a means "to smell of": huele a café, it smells of coffee. To see it in a real sentence: Ayer la casa olió a pintura. — "Yesterday the house smelled of paint.".

The only accent to watch is on the third person singular, olió, and on the first person singular, olí.

The preterite tense vs the closest tenses
Preterite — one finished event vs Imperfect — background or past habit
The preterite reports one finished event — it happened, it ended, the story moves on. The imperfect describes the background — what was happening, what used to happen, how things were. In a story the two work together: the imperfect sets the scene and the preterite tells what happened in it.
- Preterite — one finished event: Yo olí el pan recién hecho. — "I smelled the freshly baked bread."
- Imperfect — background or past habit: Yo olía el pan recién hecho. — the same idea, placed in the imperfect.
Preterite — what happened vs Present — the rule or habit now
The preterite reports what happened at a finished moment in the past. The present states the rule or the habit that is still true now. Use the preterite when you are telling a story about yesterday, and the present when you are stating how things are in general.
- Preterite — what happened: Tú oliste las flores del jardín. — "You smelled the garden flowers."
- Present — the rule or habit now: Tú hueles las flores del jardín. — the same idea, placed in the present.
Preterite — finished time vs Present perfect — past connected to now
The preterite belongs to a finished time — yesterday, last year, on Monday. The present perfect connects the past to the present — something that happened recently, or that has happened up to now. If the time is finished, use the preterite; if the time reaches into the present, use the present perfect.
- Preterite — finished time: Mi madre olió el gas y llamó al técnico. — "My mother smelled the gas and called the technician."
- Present perfect — past connected to now: Mi madre ha olido el gas y llamó al técnico. — the same idea, placed in the present perfect.

c) olí — The sentence needs the yo form in the preterite: olí. The other options are the wrong person or the wrong tense.
a) olí — The subject is yo, so the preterite form is olí.
a) olimos — Nosotros takes olimos. In the preterite the nosotros ending for -er verbs is -imos, attached to the stem ol-.
a) Mi madre olió el gas y llamó al técnico. — Mi madre olió el gas y llamó al técnico. is correct: the verb agrees with its subject. The other sentences use the wrong person or the wrong tense.
a) olió — oler is a stem-changing verb, so the él/ella form is olió, with the changed stem. The nosotros form keeps the plain stem, and the form without the change is not Spanish.
b) olimos — The subject is nosotros/as, so the preterite form is olimos.
d) oliendo — The gerund is oliendo. It is the form you use with estar for the progressive (estar + gerund), and it is not the past participle olido.
