Examples:

Proverbs:
> You're like sardines, very many but only enough for one wrapped piece of fish.
Fish are properly wrapped individually in a leaf for cooking, but sardines are so small that a bunch of them may be wrapped together to make up only one small bundle. The idiom may be applied to a numerous but weak enemy or to a clan that is large but ineffective as in raising money for its members, or for a large group of workers who do not accomplish very much.
> It's like the foam of the sea, which forms unexpectedly and then disappears.
It's a matter that comes up for lengthy discussions and then is dropped without resolution or effect. Some things, like sea foam, drift on without settlement. Endless discussion without reaching agreement.
> He gets his law from the streets.
Rael has the general meaning "way," applicable both to method and to a street. The implication is that if a child will not learn from his parents, he will learn the hard way from experience. It may be used in the positive sense of someone who is quick to learn from experience.
> Like a racing canoe of Ngerchelong, fast by word of mouth.
Apparently refers to a canoe race of the past when a club of Ngerchelong lost after having given verbal display of greatness. Refers to the bluff or braggart (all-mouth, no action).
> Like Ngiramesemong, rehashing what has been finished.
Pertains to a person who repeatedly reminds another of past favors or continually recalls the mistakes of others. (My sources no longer recalled the episode or story from which this idiom derives.)
More Examples:
> I was sleeping on the bench and listening to the waves breaking on the shore.
> Take out your books.
> She started the fire.
> I will shower tonight.
> Most Americans living in Belau love Belau and future compact towards the island.
