Lesson 18. Commands and requests

Now let's look at how to urge someone to do something: commands.

To make an imperative sentence, you just replace "do" with the word ko.

ko
The imperative "you"; it covers a wide range from strict commands to polite requests.

ko stali ta Stay there.

ko na kusru mi Don’t be mean to me.

lo prenu cu prami ko Be someone that people love.

So putting na before the selbri with ko means "don't..." That last example is interesting—it takes a moment to wrap my head around it.

ko can fill any terbricmi — the command is “make this bridi true.”

So instead of ordering someone to love you, lo prenu cu prami ko is more like "Behave in a way that results in people loving you."

ko alone already spans “do it” through “please do”; that covers most imperative needs.

If you want to add more nuance—like making a polite request, a suggestion, or granting permission—you can use attitudinals at the start of your sentence:

.e'o
request
.e'u
suggestion
.e'unai
warning against
.e'a
permission
.e'anai
forbiddance
.e'i
constraint / obligation
.e'inai
release / “up to you”

(Plus pei for “may I?” patterns — see below.)

Some sentences keep do instead of ko — proposals and permissions aren’t always straight imperatives.

We’ll go deeper into the nai suffix in the finale. But generally, if it's a suggestion or a request rather than a direct order, it's very common to use do instead of ko.

You can also use the word pei to turn an attitudinal into a question:

pei
Turns the preceding attitudinal word into a question.

.e'a pei mi lasna do lo bitmu lo dunja badna May I stick you to the wall with a frozen banana?

― nai No.

I see. So nai flips the attitude, similar to how to'e flips a brivla. This is getting deep!

True or false

Pick whether each statement is true or false according to the lesson.

  1. ko only swaps with x1 of do.

  2. .e'o, .e'u, .e'a are attitudinals for request, suggestion, and permission (in that order).

  3. .e'i means “constraint”, and .e'inai means “forbidden”.

  4. Putting pei right after .e'a can form “Is it OK if …?”.

  5. ko by itself covers a wide range from crude commands to polite requests.
