Proverbs:
> Like the kingfisher, chattering while taking to wing.
The kingfisher, a restless, bullying bluebird, may be heard to chatter loudly when flying up from the ground or from a perch. The saying applies to one who suddenly spouts instructions to a group, then leaves, or to a leader at a meeting who impatiently interrupts a discussion with a burst of pronouncements, then ends the meeting.
> Are there any who spear at the ground and miss?
Used to describe something that is easily accomplished.
> Like the uul [Cettria cantans?] with its house open, calling for rain.
The uul may be heard to call out usually just before it rains; some say that it is calling for rain. This seems foolish, since the bird constructs its house with an opening at the top that will let rain in. A person who makes a decision or starts some action without adequate preparation is likened to the uul.
> He's like the sea urchins between Ngiwal and Melekeok, on the ocean floor with its cover.
The sea urchin can be seen lying quietly on the lagoon floor, occasionally with a leaf like a hat covering its head. Applied to a man who acquires a wife or great wealth without working for it.
> 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.
More Examples:
> Where are you from?
> I went to fertilize my taro patch.
> What are the odds that we win the baseball game?
> Yigo is located on the north side of the island.
> No, so I really have to study tonight.
