Getting started with Lojban (alpha)
<27. Tenses 3
Tenses 3
As previously mentioned, Lojban tenses treat time and space fundamentally the same – saying that I worked a long time ago is not grammatically different than saying I work far away to the north. Let's meet a few spacial tenses:
zu'a sumtcita: left of SUMTI.
ri'u sumtcita: right of SUMTI.
ca'u sumtcita: in front of SUMTI.
bu'u sumtcita: at the same place as SUMTI (spacial equivalent of ca).
Now, let's see a few examples of their usage:
| Sentence | Possible translation |
|---|---|
| zu'a do tavla lo prenu | To the left of you, (somebody) is talking to a person. |
| zu'a ku do tavla lo prenu | To the left, you are talking to a person. |
| do zu'a {ku} ctuca | To the left, you are teaching. |
| ri'u lo ctuca ku lo mi pendo cu ciska | To the right of the instructor, my friend is writing. |
| ca'u lo skami ku lo vecnu cu tavla lo te vecnu | In front of the computer, the seller is talking to the buyer. |
| bu'u lo zdani ku mi gleki | At home, I am happy. |
| bu'u ma do gleki | Where are you happy? |
Also, if spacial and temporal tenses are mixed, the rule is to always put temporal before spacial. Here are a few examples:
| Sentence | Possible translation |
|---|---|
| mi ba {ku} zu'a {ku} ctuca | I will teach to the left. |
| ba {ku} ri'u lo ctuca ku lo mi pendo cu ciska | To the right of the instructor, my friend will write. |
| mi pu {ku} gleki bu'u lo zdani {ku} | At home, I was happy. |
Pretty, intuitive, right?
But what if we wanted to say that something happened shortly to the left, or will happen far into the future? Luckily, Lojban has words for that, too.
vi location tense distance: here at ... ; at or a very short/tiny distance from ...
va location tense distance: near to ... ; there at ...; a medium/small distance from ...
vu location tense distance: far from ... ; yonder at ... ; a long distance from ...
zi time tense distance: instantaneous-to-short distance in time
za time tense distance: medium distance in time
zu time tense distance: long distance in time
Notice the vowel order i, a and u. This order appears again and again in Lojban, and might be worth memorizing. Short and long are always context dependent, relative and subjective. Two hundred years is a short time for a species to evolve, but a very long time to wait for the bus.
Let's see a few examples:
| Sentence | Possible translation |
|---|---|
| mi pu {ku} zu {ku} gleki bu'u lo zdani {ku} | A long time ago, I was happy at home. |
| do vu {ku} gleki | Far away, you will be happy. |
| lo gerku {ku} pu {ku} zi {ku} gleki | Shortly ago, the dog was happy. |
| mi ba {ku} zu'a {ku} vi {ku} ctuca | I will teach shortly to the left. |
| lo va mlatu cu melbi | The moderately distant cat is beautiful. |
Note: People rarely use zi, za or zu without a pu or ba in front of it. This is because most people always need to specify past or future in their native language. When you think about it Lojbanically, most of the time the time-direction is obvious, and the pu or ba is superfluous!
It is also possible to say that something happened two meters to the left, or will happen three days into the future; but this will only be covered in a future lesson.
Practice
As usual, before proceeding to the next lesson, get some practice with interactive exercises – look for the "Practice" button nearby!
Beware that exercises loop indefinitely, so feel free to stop once you feel you've had enough. And be sure to revisit exercises on different days, to benefit from the spacing effect.
