To express that something has a certain property to a higher degree than something else, place the quantifier mas ‘more’ before an adjective or adverb. The compared entity is introduced using the preposition cem ‘than’.

Ya mas silni cem makika (ya). – She is stronger than her brother.
[But] makika i [run] mas ku [fast] cem ya. – But the brother runs faster than she.

Mas can also be used before nouns:

Mas jen li lai cem nas (li) [expect]. – More people came than we had expected.

To express the superlative – a higher degree than everything else – ol mas ‘most’ is used. This can be considered an abbreviation of mas … cem ol otra ‘more than all others’.

Ya ol mas silni. – She is the strongest.

The opposite of mas is men ‘less, fewer’.

Ya men [intelligent] cem [wife] (ya). – He’s less intelligent than his wife.
Men jen li lai cem nas (li) [expect]. – Fewer people came than we had expected.

Ol men ‘least’ is used in the same way as ol mas.

XXX Add example, including the selection preposition (de ‘of’?).

For expressions of equality, tan … cem ‘as … as’ is used:

Ya tan gau cem makika (ya). – She’s as tall as her brother.
Ya pia [run] tan ku [fast] cem makika. – She also runs as fast as her brother.

As usual, tan can also be used before nouns:

Tan jen li lai cem nas (li) [expect]. – As many people came as we had expected.
