Use mute. Conserve the Numbers.

Okay, so it's a bad idea to use the numbers when you don't absolutely need them. So, instead, we use mute for any number higher than two:

jan mute li kama.

Many people came.

Of course, this is still pretty vague. mute in the above sentence could mean 3 or it could mean 3 000. Fortunately, mute is just an adjective, and so we can attach other adjectives after it. Here's what you might say if there were lots and lots of people:

jan mute mute mute li kama!

Many, many, many people are coming!

More than likely, that sentence is saying that at least a thousand people are coming. - Now suppose that you had more than two people but still not very many. Let's say that the number is around 4 or 5. Here's how you'd say that:

jan mute lili li kama.

A small amount (of) people are coming.
