This is an overview of the verb conjugations required for Duolingo Level 2 (Brazilian) Portuguese.

For a detailed guide, see “Modern Brazilian Portuguese Grammar” by John Whitlam. You could also check Reverso Conjugations, although it seems to use European Portuguese spelling rules.

Throughout I’ve tried to be consistent in marking irregular forms in red, distinguishing between forms where

• only the stem is irregular (eu durmo)
• only the inflection is irregular (eu estou)
• both both are irregular (eu vou)

Regular verbs

Category -ar

Notes

• In European Portuguese, the first person plural preterite is spelled “falámos” instead of “falamos”.
• For verbs ending in -car: -c- becomes -qu- before -e: tocar, eu toquei.

Category -er

Category -ir

NOTE: for verbs ending in -guir, -gu- becomes -g- before -o or -a (e.g. “distinguir” → “distingo”).

Subcategory: -e- in the stem

The -e- changes to -i- in the first person singular present.

Subcategory: -o- in the stem

The -o- changes to -u- in the first person singular present.

Semi-irregular verbs

ler “to read”

ouvir “to hear”

pedir “to ask”

perder “to lose”

Irregular verbs

dar “to give”

Cautious of the difference in pronunciation between “demos” and “deram”.

dizer “to say”

estar “to be”

fazer “to do, make”

haver “to have”

This is only used in the third person singular, and never with a subject: “Há um carro lá”, “Há carros lá”.

ir “to go”

poder “to be able”

querer “to want”

saber “to know”

ser “to be”

Note: preterite forms identical to ir “to go”.

ter “to have”

ver “to see”

vir “to come”
