da (KOhA1)

something 1. Logically quantifiable singular variable.

ro da poi gapkla cu nitkla
Everything that goes up, comes down.

de (KOhA1)

something 2. Logically quantifiable singular variable.

su'o da su'o de gapkla gi'e stali
Something goes up somewhere and stays there.

di (KOhA1)

something 3. Logically quantifiable singular variable.

pa da broda ijo ge su'o de broda gi ro di poi broda cu du de
Exactly one thing1 is a broda iff some thing2 is a broda and every thing3 that is a broda is that thing2.

Notes

• da, de, di are singular variables because they take values one at a time. The quantifier indicates the number of values it can take such that with each of those values the relationship is true. A plural variable could take more than one value at once to satisfy a predicate.
