Proverbs:
> It's like the way they eat in Ngeraus (where food is scarce): as soon as they get to like or enjoy the food, it's gone.
Just as something becomes popular, it becomes unavailable. Ngerraus is a small village in Ngchesar (central Palau). The idiom suggests a person who begins to feel hungry just as the food runs out. The reference is to the meager food resources of a small village. In contemporary Palau the idiom may be applied to some popular import that soon disappears from the shelves of the stores.
> Like the chelechelui [fish].
The chelechelui fish reputedly resists rotting when cooked, remaining firm long after other fish would be soft and rotten. The saying implies mature persistence.
> He's like Chelebesoi of Ngeriil, dead in a fishtrap not his own.
A man named Chelebesoi (also the name of a fish) was robbing another man's fish trap when a head-hunting party came by and removed his head. He lost both his head and his reputation. The idiom may apply to one who gets hurt while trying to do someone else's job.
> Like the bathing of the terriid.
The terriid, a bird, takes a quick splash bath, hardly a complete bathing. The idiom applies to a ducking one may get when a boat swamps, or to a wetting with spray. More generally, it is applied to a task done with haste rather than with care. It can be applied also to a brief acquaintance.
> Like the sea-horse worm.
The kobesos is a small eel-like creature with the head of a sea horse. It never faces another fish directly but always shies away sideways. The saying is applied to a person who is too bashful or backward in a public situation.
More Examples:
> The drum was overfull and flowed over the top.
> Sit on the opposite side of the window
> My uncle's wife has an obligation to go to today.
> The bench is wobbly so we might fall.
> We went to the movies
