Phrases and clauses
Phrases and clauses are groups of words in Toki Pona grammar.
Phrases
Phrases are groups of consecutive content words, split by particles or prepositions. The first word in a phrase is the head, and the others, if any, are modifiers. Phrases may be called noun phrases, especially in subject, direct object, or prepositional phrase position. If a phrase is used as its own sentence fragment, it is called an interjection.
Clauses
Clauses are parts of a sentence with a subject and predicate. In standard use, sub-sentence clauses only occur with la, which splits the sentence into a context phrase or context clause, and a main clause. The word ni can function as if it introduces a relative clause, but grammatically it is a new sentence, not a clause.
