Regular vs. Irregular Verbs

In previous lessons, you learned the verb ser to be - permanent, a common irregular verb. (As if learning 50 conjugations of a verb wasn’t enough, we also have to watch out for the dreaded irregular verbs! 🙈) Why are they called that? Well, they are irregular because they don’t follow the same conjugation patterns as regular verbs. To make sure you’re ready to face more verbs in the coming lessons, let’s look at both regular and irregular verbs in Portuguese.
Hang on to your hats! 🎩👒

Irregular verbs happen in English too

Have you noticed that English also has irregular verbs? The verb “to be” is a good example – could you explain to a beginner why “you is” or “she am” is incorrect?
You can’t! The correct conjugations just have to be memorized because they come from an irregular verb.

Irregular verbs in Portuguese

In Portuguese, when you conjugate a regular verb, you take the root (which doesn’t change throughout the conjugation) and you add an ending, which varies according to the subject, number, and tense. Depending on how the verb ends (-ar, -er, or -ir), these endings are always the same for regular verbs.
With irregular verbs, it’s more complicated.
Some irregular verbs present changes in the root, others in the termination (ending) rules, and others in both. However, being classified as irregular doesn’t necessarily mean that the entire conjugation becomes weird and unfamiliar. Sometimes it’s only in certain forms and sometimes a Portuguese verb can be irregular in one tense (i.e. present tense) but regular in another… Que confusão! What a mess!

Changes in the root:

  • Medir To measureEu meço I measure (instead of “Eu medo”)
  • Trazer To bringEu trago I bring (instead of “Eu trazo”)

Changes in the ending:

  • Fazer To doEle fazHe does (instead of “Ele faze“)
  • Estar To beEu estouI am (instead of “Eu esto“)

How can you tell whether a verb is regular or irregular?

There is no way to know if the verb will be regular or not just by looking at the infinitive form of the verb. Again, you just have to memorize them over time!
However, depending on how different an irregular verb is from what it “should” be, it is possible to group the irregular verbs in Portuguese into the following groups:

Strong Irregular Verbs examples:

    • Estar To be
    • Dar To give
    • Ter To have
    • Saber To know
    • Fazer To do
    • Querer To want
    • Poder To be able to
    • Dizer To tell

Weak Irregular Verbs examples:

    • Ouvir To hear
    • Perder To lose
    • Medir To measure
    • Pedir To ask

Help! 😧

Remember, you can always reference our Verbs section for help with conjugating regular and irregular verbs in different tenses. 😌


    • Hey, Shirley. Oh, it certainly could – “ter” is also a highly irregular verb. This is not an extensive list, though, just a few examples. I’ll add it anyway, since it’s a verb that we use all the time and good to know.

  • In the third person plural of “ver” and “ler” you need two “e”s because you need eyes to see and read and “eyes” has two “e”s; whereas, you don’t need eyes to have (ter) something (one “e” with a circumflex)

    • That’s precisely what Portuguese teachers often say to help students memorize the different conjugations 🙂 Definitely don’t take it literally, but keep it in mind as a convenient mnemomic.

  • God, its much harder than i thought!
    I suppose there is no easy way to learn verbs, it just depends upon how good your memory is as to how quickly you can memorise them!

    • For the irregular ones, it does come down to some memorization. Fortunately (or unfortunately depending on how you look at it!) many of the most common verbs are irregular, which means you’ll also often hear certain conjugations in context. That can make it easier to pick some of it up within common phrases without explicitly having to memorize.

    • Good question – this is a tough one. We actually talk about this in one of our podcasts: As Senhoras Que Bebem Cerveja . Skip to about the 5:50 mark and listen to Rui’s pronunciations. It’s hard to hear, but basically with veem, the first e is more like “eh”, whereas with vêm it’s more like a nasalized “ay”.

  • The difference between the conjugation for ver and those for vir has always been difficult for me. But I like the “you need two eyes to read, so therefore you need two e’s in the plural conjugations for ver” tip.
