It depends on where you're using the word "more".

If describing a larger quantity of something: "We need more food." Then either POGASS (for the uncountables) or POGAAN (for the countables). In this specific case: MU LAAN POGASS KIP.   ZOK: "most" can also expand to mean "more" but I'm not sure if it can be used here.

If describing difference or to compare: "You look more beautiful." Then ZOK is the ZOK general word. HI NUZ(?) ZOK BRIT. Additionally, I guess NOL: "from" can be used as "than".

In cases like "You are more than a friend to me." Then instead use PRUZAAN: "better". HI LOS PRUZAAN NOL (AAN) FAHDON WAH MUN(?)
