The rule therefore stands thus : All Nouns in mu-, which take the accent on the mu-, form the Plural in miu-. The instances quoted on page 546 will serve to illustrate this. Mungùla, warmth, might be expected to take its accent on the second syllable as though nmngùla, but as the accent is on the first syllable, it is clear that the u is radical, and that the word is a contraction of mu + ùngula, and its Plural is therefore mi + ùngula=miùngula.
