Verbs: The Imperative

As already mentioned in the section on ‘moods’, the imperative mood and its tense refer to commands, instructions, or requests for action (there is only one tense in the imperative mood, so the term ‘imperative tense’ is rarely used – it is usually just referred to as the ‘imperative mood’).

The imperative forms of verbs cannot be conjugated in the first person singular, because you can’t really request or command yourself to do something. It is also quite rare for the imperative to be used in the first person plural, but it does happen with limited number of verbs (eg. ‘vamos’ = ‘let’s go’; ‘vejamos’ = ‘let’s see’) - technically, this is really the present subjunctive form, but it is used imperatively. Usually, to say ‘let’s do something or other’, you use ‘vamos’ + the infinitive of the required verb. So ‘let’s eat’ would be ‘vamos comer’.

There is no real need for a true imperative form with the third person, since you can't really command someone who is not party to the conversation, but due to Portuguese using the third person as a polite way of addressing someone, the need for a third person conjugation is introduced. As with the second person plural, Portuguese borrows from the present subjunctive for this.

Technically then, the imperative only relates to the second person singular and plural, and even then, only for affirmative actions, so some reference works will only give you 2 words for the imperative. I will give you the full conjugations though (borrowing from the present subjunctive for the other forms), as it is helpful to think of these additional forms as being imperative.

The rules for creating imperative forms are a bit topsy-turvy. It’s probably 50/50 whether it takes more time to learn the rules or just to memorise the endings as with any other conjugation. It certainly won’t do any harm to try studying the rules though, and it might help you to remember the endings, so here goes…

For first conjugation verbs, use the present indicative tense, but swap the ‘a’ for an ‘e’ in the ending. For second and third conjugation verbs, you also use the present indicative, but swap the ‘e’ or ‘i’ for an ‘a’ in the ending. The exception to this is the second person – where you don’t exchange the vowels, but you do knock of the last ‘s’. So…

 

trabalhar = infinitive (to work)

trabalh = stem (work)

trabalhas = second person singular present indicative (you work)

trabalha = second person singular imperative (work!)

trabalham = third person plural present indicative (they work)

trabalhem = third person plural imperative ([all of you] work!)

escrever = infinitive (to write)

escrev = stem (write)

escrevemos = first person plural present indicative (we write)

escrevamos = first person plural imperative (let’s write!) – note this would be a very formal way of saying this.  More common would be ‘vamos escrever’.

escreve = third person singular present indicative (he writes)

escreva = third person singular imperative (write!)

assistir = infinitive (to attend; to watch)

assist = stem (attend; watch)

assiste = third person singular (she watches/he attends)

assista = third person singular imperative (watch!/attend!)

Irregular imperatives…

Thanks Written by Carolyn on 2006-05-17 13:02:24 IP: 80.3.128.8 I've got an exam in Portuguese tomorrow and I always forget how to form the imperative - this has been very helpful, thanx.

Appreciate this assistance Written by Rhonda on 2007-04-27 16:45:09 IP: 190.80.29.34 I am presently learning about the imperative forms of the verbs in my Portuguese class and it was a bit confusing. Your explanations have helped a great deal. I appreciate it very much.

I'm confused... Written by Blaise on 2008-01-09 16:34:45 IP: 89.181.110.114 I read that the subjunctive tense can be used for commands. I suppose since the subjunctive usually expresses some doubt, it is more assertive to use the imperative for commands?

Subjunctive and Imperative Written by Krystoffer on 2008-12-31 04:52:58 IP: 189.32.120.249 The present subjunctive should be used, instead of the imperative mood, for negative commands.    Thus, for affirmative commands, the Imperative mood:  COME! (eat!),    but for negative commands, the Present tense of the Subjunctive mood:  NÃO COMAS! (do no eat!)    Brazilian Portuguese hardly ever follow that rule (I'm Brazilian and we use Imperative for both), but European Portuguese may observe that distinction.
