First Steps in Lojban

Lesson 8. Conversion (SE)

Next, let's look at how we can manipulate our selbri—which, in practice, opens up a whole new set of tricks for our sumti.

Manipulation, huh? Sounds like we're getting into the advanced stuff!

It’s actually very intuitive. The SE series of words can be attached to a selbri to swap its x1 slot with one of the others (x2, x3, x4, or x5).

se
swap x1 and x2
te
swap x1 and x3
ve
swap x1 and x4
xe
swap x1 and x5

"Swap"? How does that work in practice?

Example with klama:

klama
x1 goes to x2 from x3 via x4 by means x5

mi klama ta ta se klama mi I go there.

mi klama zo'e ti ti te klama zo'e mi I go from here.

mi klama zo'e zo'e tu tu ve klama zo'e zo'e mi I go via there.

mi klama zo'e zo'e zo'e ti ti xe klama zo'e zo'e zo'e mi I go using this.

I see! So se swaps places 1 and 2, te swaps 1 and 3, and so on.

Exactly. These conversion words don't change the underlying meaning—they just change the perspective of the sentence.

Is it really worth the extra words?

Koshon

Definitely! For one thing, if you only care about a recipient or a tool and don't care about the giver or the user, it saves you from having to use a bunch of zo'e:

[zo'e] klama zo'e zo'e zo'e ti ti xe klama [zo'e] (Someone) goes using this.

Hmm, I guess that is cleaner.

But the real magic happens when you combine it with lo! This lets you turn any place slot into a description or title:

lo klama ku goer (x1 of klama)

lo se klama ku destination (x1 of se klama = x2 of klama)

lo te klama ku origin

lo ve klama ku route

lo xe klama ku vehicle / means

Whoa, that's a huge power-up for our descriptions!

Oh, I get it now! That's what you meant by "widening sumti tricks."

Bingo. Whenever you're stuck, just remember: with se/te/ve/xe, you can use lo to extract any slot from x2 to x5.

True or false

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

  1. se swaps x1 and x2.

  2. xe swaps x1 and x4.

  3. lo se citka ku is a sumti meaning “something edible”.

  4. se, te, ve, xe attach immediately before the sumti they modify.
