because of the way that things like stress assignment and the morphological process of reduplication are affected by it. Dorsey's Law can apply within a single morpheme, as in /pra/ becoming [para] in the word paras '(be) wide, flat', or across morpheme boundaries, as in /šra/ becoming [šara] in the word šaraše 'you go there,' where š is the second person pronominal prefixing to the verb rahe 'to be going there.' Metrical structure Ho-Chunk is a mora counting, but syllable accenting language. The stress placement of words spoken in isolation is extremely regular. Single-syllable words always have a long vowel (two moras), and stress falls on the first mora (e.g. áa 'arm'). Two-syllable words have two moras, and primary stress falls on the second mora (e.g. wajé 'dress'). In words longer than two syllables, primary stress most often falls on the third syllable, with secondary stress on each even numbered vowel after the point of primary stress (e.g. waǧįǧį́ 'ball,' or hocįcį́k 'boy'). A few rare examples of words with primary stress not on the third syllable include booráxux 'you break something into pieces' and gikąnąhé 'to invite somebody.' These and other exceptions are a result of syllable weight affecting stress location. As seen in booráxux 'you break something into pieces,' when one of the first two syllables of a multiple-syllable word is a heavy syllable, then the main stress falls on the second syllable Generally when words are spoken in sequence to form sentences, each retains its own stress domain. However, when two or more words are compounded, they are treated as a single word and form a new single stress domain in which the aforementioned patterns apply. Examples include hąąbókahi 'every day' (a compound consisting of hąąp 'day' and hokahí 'every') and wąągwácek 'young man' (wąąk 'man' and wacék 'young'). Ho-Chunk's stress system is substantially different from that of other Siouan languages, which have main stress on the second syllable or second mora. It is theorized that Ho-Chunk underwent a stress shift one mora to the right at some point in its history. Orthography The official Ho-Chunk orthography derives from an Americanist version of the International Phonetic Alphabet (IPA). As such, its graphemes broadly resemble those of IPA, and there is a close one-to-one correspondence between graphemes and phonemes. The orthography differs from IPA in that the nasal vowels are indicated using an ogonek. Thus, /ĩ/, /ũ/, and
