Omo To suck; omoaga, bulky cloud;  ragi omoaga cumulus; omoomo; to suck repeatedly, to suckle; omotahi, to win everything at a game (lit: to suck whole): omotahi-mai-á e au, he has cleaned me out; omotohi, full (of the moon); ku-omotohiá te mahina, the moon is full. Rima omo, infidelity, faithless, unfaithful. Omoomo, to smack the lips, to suck the breast, to smoke tobacco, to taste of; hakaomoomo, to suckle, to paint. Ta.: Omotu, an ember, a coal. Mq.: komotu, omotu, firebrand.

Omotahi is 'to win everything at a game' ('to suck whole'), which reminds me about the Red Queen and her fiery behaviour.

Omotu is a firebrand (or ember), and also the first part of Mokuola. Like in Hilo / Ohiro the added O does not seem to carry much more meaning than being a form of appreciation. In the Japanese language O signifies 'venerable', for instance in okasan (mother) and otya (green tea).

But the fundamental meaning of omo is clearly 'to suck'. We can in the full moon bodyshape indeed see there is not room for any more - 'the sucking is finished', omotohi, and Moon is full:
