# Esperanto/Lesson 5

In this lesson we will introduce Esperanto's correlatives and talk about the imperative.

## Correlatives

In English, most question words begin with wh- and many of the short words to refer to their answers (the demonstratives) begin with th- (e.g. where — there). In Esperanto, this is similar, but fully regular and more expansive. These words are together called the "correlatives". In this lesson we will focus on the question words and their accompanying demonstratives. All correlatives have a beginning (which indicates whether it is a question word, demonstrative, etc.; these always end in -i) and an ending (which indicates the type of information referred to). Those in bold in the chart below are the subject of this lesson.
The ti- words do not specify distance. Therefore, tiu can mean both "this one" and "that one" and tie can mean both "here" and "there". When distance is unclear, the word ĉi, not to be confused with the correlative prefix "ĉi," may be used without any suffix to indicate something closer at hand. For example, "Tiu ĉi tablo" would mean the speaker is indicating this table nearby, rather than that table further away.
| Correlatives | ki- | ti- | i- | ĉi- | neni- |
| -u (person/thing) | ki-u (who, which one) | ti-u (this/that one) | i-u (some/a person/thing) | ĉi-u (every person/thing) | neni-u (no person/thing) |
| -o (thing) | ki-o (what) | ti-o (this/that) | i-o (some thing) | ĉi-o (every thing) | neni-o (no thing) |
| -a (type/kind) | ki-a (what type, which kind) | ti-a (this/that type/kind) | i-a (some/a type/kind) | ĉi-a (every type/kind) | neni-a (no type/kind) |
| -e (place, location) | ki-e (where) | ti-e (here/there) | i-e (some place) | ĉi-e (every place) | neni-e (no place) |
| -am (time) | ki-am (when) | ti-am (then) | i-am (some time) | ĉi-am (every time, always) | neni-am (no time, never) |
| -om (quantity) | ki-om (how many) | ti-om (this/that many) | i-om (some amount) | ĉi-om (every amount) | neni-om (no amount) |
| -es (ownership) | ki-es (whose) | ti-es (this/that one's) | i-es (some/any one's) | ĉi-es (everyone's) | neni-es (no one's) |
| -al (causation) | ki-al (why) | ti-al (because of this/that) | i-al (for some reason) | ĉi-al (for all reasons) | neni-al (for no reason) |
| -el (method) | ki-el (how, in what way) | ti-el (this/that way) | i-el ((in) some way) | ĉi-el (in every way) | neni-el (in no way) |
In general, it is good to be specific in what you ask (this is true regardless of the language you're speaking). For example, if you want to ask about the topic of a lesson, it is best to ask "Pri kio temis la leciono?" (About what was the lesson?, lit. "about what did the lesson talk?"). If you ask "Kia estis la leciono", don't be surprised if you get an answer in the spirit of "(Ĝi estis) bona." or "(Ĝi estis) longa.", because you've asked for a characteristic of the lesson. To ask how the lesson went, you can better ask something like "Kiel fartis la leciono?", then you'll get an answer like "(Ĝi fartis) bone.".

### Examples

* Kiel estas tiu viro? – How is that man?
* Kia aŭto estas ĝi? - What kind of car is it?
* Li estas malagrabla. – He is unpleasant.
* Kie estis tiu leciono? – Where was that lesson?
* Tiu leciono estas en interreto. – This lesson is on the internet.
* Kiu povas lerni Esperanton? – Who can learn Esperanto?
* Ĉiuj povas lerni Esperanton! – Everyone can learn Esperanto!

### Ke vs. kiu

Both ke and kiu can sometimes be translated as 'that'. Kiu is used as a general relative pronoun and refers to specific people or things, whereas ke does not refers to something specific and is used to link . In the former case, the word 'that' can be changed to 'which' with little change in meaning; in the latter it cannot:
* Mi vidis, ke via hundo mordis vian najbaron. – I saw that your dog bit your neighbor.
* Sekve via hundo mordis katon, kiu estis en la strato. – Next, your dog bit a cat that was on the street.
* Tiu montris al mi, ke tiu viro ne faris tion. – That showed (to) me that that man did not do that.
* Vi vidis ke la birdo kiu estis kun mi, flugis. - You saw that the bird which was with me, was flying

## Imperative

To command or request something from the listener, a verb's infinite ending -i is replaced with -u and 'vi' is not used.

### Examples

| Sentence | Meaning |
| Legu tion libron. | Read that book. |
| Ne iru al la parko. | Don't go to the park. |
| Dormu bone. | Sleep well. |
| Lernu Esperanton bone. | Learn Esperanto well. |
| Ne faru tion! | Don't do that! |
| Manĝu malpli viandon | Eat less meat. |
