Recall that there are -AR, -ER, and -IR verbs that have a stem change in the present tense. However, they don't all behave the same in the preterite.
Stem-changing -AR and -ER verbs
-AR and -ER verbs that have a stem change in the present tense, don’t have a stem change in the preterite tense. For example:
- (devolver)
Yo devolví los pantalones por ser muy grandes. (I returned the pants for being too big.) - (volar) El billonario voló a España para comprar zapatos de cuero. (The billionaire flew to Spain to buy leather shoes.)
Or, in table form:
| Present | Preterite | Present | Preterite |
|---|---|---|---|
|
e → ie cerrar cierro cerramos cierras cerráis cierra cierran |
no stem change cerrar cerré cerramos cerraste cerrasteis cerró cerraron |
o → ue volver vuelve vuelven |
no stem change volver volví volvimos volviste volvisteis volvió volvieron |
Stem-changing -IR verbs in the preterite
However, the -IR stem-changing verbs *do* have a change in the preterite: but it’s only in the third person (singular and plural), and -IR stem-changers will change their stem vowel to just the first letter of the stem-change they had in the present tense.
-IR verbs that changed from “e” to “ie” in the present will change just from “e” to “i” in the preterit. -IR verbs that changed from “o” to “ue” in the present will change just from “o” to “u” in the preterit. And -IR verbs that changed from “e” to “i” in the present will do just that in the preterit.
Conjugation of stem-changing -IR verbs in the preterite
| Present: (e-ie) Preterite: (e-i) | Present: (o-ue), Preterite: (o-u) | Present: (e-i), Preterite: (e-i) |

The best way to learn these conjugations is to say them out loud until they sound right to you. Practice, and train your ear! Once you hear the endings and changes right in your head, you’ll be able to spell them right on the page.

Stems that end in a vowel for verbs ending in -ER and -IR
- Observe that the stem of -ER and -IR verbs leer, caer, oír and huir end in a vowel: le-, ca-, o-, and hu-.
- For verbs like these, a written accent is needed on the "í" for the conjugations of yo, tú, and nosotros.
- Also for verbs like these, the vowel "i" of the ending in the conjugations of usted, él, ella and ustedes, ellos, ellas will change to "y". This is because the endings for -ER and -IR are "ió" and "ieron" (whereas, verbs ending in -AR are just "-o" and "-aron").
| Leer - to read | Caer - to fall | Oír - to hear | Huír - to flee |
|---|---|---|---|
|
leí leímos leíste leyó leyeron |
caí caímos caíste cayó cayeron |
oí oímos oíste oyó oyeron |
huí huímos huíste huyó huyeron |
Note that in the conjugations above, the endings are in bold and the spelling change is indicated in blue.
