Prepositions

English Wikipedia has an article on
Prepositions.

A preposition is a type of content word used to express spatial or temporal relations or to mark various semantic roles. The phrase formed by a preposition together and the complement that follows it is called a prepositional phrase.

Function

A prepositional phrase gives context to the predicate or subject of the sentence. They describe the location, cause, purpose, quality, or means of the action, actor, or acted-upon. Toki Pona's prepositions are kepeken, lon, sama, tan, and tawa.

mi sitelen e ni kepeken toki lili .

mi sitelen e ni kepeken toki lili.

I wrote this by means of few words.

ilo ni li pona tan ni : ona li pakala ala.

ilo ni li pona tan ni: ona li pakala ala.

This tool is good because of this: it doesn't break.

Prepositions vs. transitive verbs

Difference between the phrases mi tawa tomo and mi tawa e tomo.

In the sentence A li B e C, the subject A causes the direct object C to become C B.

So, in the sentence ona li tawa e telo, the subject ona causes the telo ("water") to become telo tawa ("going water"); the sentence translates as "They move the water".

In ona li tawa telo, the word tawa instead acts as a preposition. Given that tawa telo is a prepositional phrase meaning "toward water", this sentence translates as "They go to the water".

For another example:

kasi li lon ma ale

kasi li lon ma ale.

Plants exist at all of the land.
Plants are everywhere.

kasi li lon e ma ale

kasi li lon e ma ale.

Plants cause all the land to exist.
Plants created the Earth.

Modifiers

Like preverbs, prepositions are most often modified by a limited group of semiparticles.

ona li tawa ala telo

ona li tawa ala telo.

They don't go to the water.

Ambiguity

Because prepositions are not marked with any particle in standard Toki Pona, they are a bit ambiguous. For example, in ona li tawa telo, tawa telo can be taken as a prepositional phrase ("toward water"), or a noun phrase ("the going of water"; "fluid motion") if telo is taken as a modifier.

Word order

Some speakers limit prepositions to the end of a sentence, while some apply it freely.

This is an example of a free preposition placement:

waso lon telo li pilin musi　

waso lon telo li pilin musi.

The ducklings in the pond are having fun.

However, this could also mean:

The existent water ducklings are having fun.

Using la, the preposition could be shifted to the start of the sentence.

tan pakala sina la moku mi li weka a　

tan pakala sina la moku mi li weka a.

Because of your mistake, my food is gone!

jan [P U T A] li pana tawa mi e mi. ona li pana tawa mi e jan [S I T A T A].

jan Puta li pana tawa mi e mi. ona li pana tawa mi e jan Sitata.

He has given me Siddhartha, myself.

Transitive prepositional phrases

Some speakers allow an entire prepositional phrase to be used as a transitive verb followed by e.

This can be thought of in the same way as a normal transitive verb. In the sentence A li prep B e C, the subject A causes the direct object C to become C prep B.

ona li tawa telo e waso

ona li tawa telo e waso.

It moves birds to the liquid.
They sent a bird to the water.

mi tawa tomo pali nanpa luka tu tu pi kulupu [N O K A S I] e sina.

mi tawa tomo pali nanpa luka tu tu pi kulupu Nokasi e sina.

I will take you to Nokasi Corp. office number nine.

kasi li lon ma ale e kon pona

kasi li lon ma ale e kon pona.

Plants cause good air to exist at all of the land.
