Oler Examples, Sentences & Quiz in Spanish

oler means "to smell" in English, and this page shows you how it actually sounds in everyday Spanish — not just the conjugation table, but the verb in real sentences, in short dialogues, and in the mistakes learners make with it. 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. Below you will find twelve example sentences grouped by meaning, two short dialogues, the most common mistakes with corrections, and a ten-question quiz with explained answers.

Common mistakes with oler

The errors learners actually make with oler, each with the wrong form, the right form, and why the right form is right.

✗ *Ayer la casa olio a pintura (missing the accent).

✓ Correct: Ayer la casa olió a pintura.

The preterite él form is olió, with a written accent on the ó. Without it the form is misspelled.

✗ *Yo olio la flor (using the él form for yo).

✓ Correct: Yo olí la flor en el jardín.

Yo takes olí, with the accent on the í. Olió is the él/ella form.

✗ *Nosotros olemos el humo ayer (present with ayer).

✓ Correct: Nosotros olimos el humo y salimos.

Ayer and other finished-time markers need the preterite: olimos, not olemos. Olemos is the present.

✗ *Ellos olieron de café.

✓ Correct: Ellos olieron a café recién hecho.

To smell of something, use a: oler a café, oler a pintura. Never use de for the smell itself.
