I marrion-webstered "tuber", and I came up with:

1 a : a short fleshy usually underground stem bearing minute scale leaves each of which bears a bud in its axil and is potentially able to produce a new plant — compare bulb, corm
b : a fleshy root or rhizome resembling a tuber
2 : tuberosity

Reading the above, I don't think that {'oQqar} could apply to the roots of a tree.

But that's ok, since I *really* like the {wutlh Sor 'ay'mey}.

Believe me when I say, I'm gonna {wutlh Sor 'ay'mey} my brains out.
