As mentioned above, most nouns have syllable-final primary stress; there are, however, some regularized exceptions to this rule, the most common of which are nouns with lexicalized suffixes in the stem, which have stress on the penultimate syllable. Also, contractions within compounded nouns have primary stress on the contraction. There are various other exceptions, but the two mentioned above are the most frequent and the most important in helping us to understand why Yuchi nouns often appear to have irregular stress patterns.
