hai
• climb; ascend.
hai la ai
• climb a tree.
hai la kruhun
• climb a mountain.
hai loi
• embark.
hai oni
• ascend to; sail to (always from sea to land or from a smaller to a larger island).
hai oni djela
• climb up.
hai oni raha
• climb up to the house.
hai tjoi pair
• sail (or paddle) upstream.
Note: hai is evidently used with or without prefix a- (also: O-) (plur. ra-, ro-) no semantic difference whatever being perceptible; thus the forms nihai, nahai, nohai, ninahai, ninohai all mean: he climbs, ascends
