[yorwba]

Huli appears regular, but a construction like "ngui ki, ngui tebone-gonaga tebira" to mean "fifteen twos and the three of the third fifteen" does seem like quite a mouthful for 33.

[jstanley]

It's not "fifteen twos" but "two fifteens".

They're just counting how many fifteens they've got: "two complete fifteens, and 3 from the third fifteen"

Is the complexity based on pronunciation here?
