·    A. Full:

o Top: two touching, angled (SW to NE) “rugby balls”, optionally with left reinforcement of line or row of dots (or both)

o Bottom: boulder with indentation in the middle of the top

§ Cross-hatched area slightly smaller than the boulder

§ Outer edge of cross-hatched area optionally bold

Tokovinine in AT-E1168-lecture?.t0:? explains that the iconography is two eggs in a nest.

·    B. Reduced-1: top part only. Do not confuse this variant of k’u with one of the reduced variants of nu:

o k’u has a dotted line as the line reinforcement of the left edge whereas nu has a solid line reinforcement of the left edge.

o Where ku has a solid line reinforcement (e.g. the full form in TOK.p18.r2.c3), the large cross-hatched region below the “rugby balls” shows that ku is intended and not nu.

·    C. Reduced-2: left or right half only.
