The conjugation in the past indefinite of indicative

talk -er
learn -ir
live
I spoke I learned I lived

Sometimes it is necessary to change the final consonant of the root in the first person of the singular of the verbs ending in -ar. This is done to keep the pronunciation of the root offered by the infinitive indefinitely.
Example:
from c to qu → dock - docked
from g to gu → hang up - hung up
from gu to gü → find out - find out
from z to c → start - I started
de c a qu → atracar - atraqué
de g a gu → colgar - colgué
de gu a gü → averiguar - averigüé
de z a c → empezar - empecé
The verbs ending in -er and -ir that contain a vowel at the end of the root do not add an i but one and in the third person singular and plural.
Example:
read - distribute
Verbs ending in -er or -ir whose root ends in -ll or -ñ do not add an i in the third person singular and plural.
Example:
tañer - tañeron
bullir - bulló / bulleron
tañer - tañó/tañeron
bullir - bulló/bulleron
Some verbs ending in -ir require modifying the vowel of the root, e → i, or → u, in the third singular and plural person. Check the list of irregular verbs.
Example:
ask - asked, asked, asked, asked, asked, asked
sleep - I slept, slept, slept, slept, slept, slept
The verbs ending in -ducir (such as translating or driving) adopt the irregular ending -hage in the first person of the singular and substitute the c for a j in the rest.
pedir - pedí, pediste, pidió, pedimos, pedisteis, pidieron
dormir - dormí, dormiste, durmió, dormimos, dormisteis, durmieron
Los verbos acabados en -ducir (como traducir o conducir) adoptan la terminación irregular -uje en la primera persona del singular y sustituyen la c por una j en el resto.
Example:
translate -traducir - traduje, tradujiste, tradujo, tradujimos, tradujisteis, tradujeron
