[tlhIngan Hol] How would you express "root of a tree" ?

[mayqel qunen'oS]

'a. Dunbej..
but this is great indeed..

qey'Hav, 'InSep, latlh mu'mey rap je vIneHtaHvIS, qay'be'. 'ach, naDev
mu'meyvam lo'lu'chugh, vaj qay'qu'bej..
while I was requesting words for "vagina", "penis", etc, there wasn't
a problem. But if someone uses these words here, then it becomes a
problem.

'ach, pImqu'bej ghu' qay'..
but the problem is actually very different..

naDev, tornISlu', 'ej reH Qochbe'nISlu'. qay' ghu'vam'e'.
