In structure all Algonquian dialects are Polysynthetic, _i. e.,_ words composed wholly or in part of other words or generic roots. Pronunciations and inflections differ as do the words in meaning in many cases. In all dialects the most simple combinations appear in geographical names, which the late Dr. J. H. Trumbull resolved into three classes, viz.: "I. Those formed by the union of two elements, which we will call _adjectival_ and _substantival,_ or ground-word, with or without a locative suffix, or post-position word meaning 'at,' 'in,' 'on,' 'near,' etc. [I use the terms 'adjectival' and 'substantival,' because no true adjectives or substantives enter into the composition of Algonquian names. The adjectival may be an adverb or a preposition; the substantival element is often a verbal, which serves in composition as a generic name, but which cannot be used as an independent word--the synthesis always retains the verbal form.] II. Those which have a single element, the _substantival,_ or ground-word, with locative suffix. III. Those formed from verbs as participials or verbal nouns, denoting a place where the action of the verb is performed. Most of these latter, however," he adds, "may be shown by strict analysis to belong to one of the two preceding classes, which comprise at least nine-tenths of all Algonquian local names which have been preserved." For example, in Class I, _Wapan-aki_ is a combination of _Wapan,_ "the Orient," "the East," and _aki,_ "Land, place or country," _unlimited;_ with locative suffix (_-ng,_ Del., _-it,_ Mass.), "In the East Land or Country." _Kit-ann-ing,_ Del., is a composition from _Kitschi,_ "Chief, principal, greatest," _hanné,_ "river," and _ing_ locative, and reads, "A place at or on the largest river." The suffix _-aki, -acki, -hacki,_ Del., meaning "Land, place, or country, _unlimited,_" in Eastern orthographies _-ohke, -auke, -ague, -ke, -ki,_ etc., is changed to _-kamik,_ or _-kamike,_ Del., _-kamuk_ or _-komuk,_ Mass., in describing "Land or place _limited,_" or enclosed, a particular place, as a field, garden, and also used for house, thicket, etc. The Eastern post-position locatives are _-it, -et, -at, -ut;_ the Delaware, _-ng, -nk,_ with connecting vowel _-ing, -ink, -ong, -onk, -ung, -unk,_ etc. The meaning of this class of suffixes is the same; they locate a place or object that is at, in, or on some other place or object, the name of Which is prefixed, as in Delaware _Hitgunk,_ "On or to a tree;" _Utenink,_ "In the town;" _Wachtschunk,_ "On the mountain." In some cases the locative takes the verbal form indicating place or country, Williams wrote "_Sachimauónck,_ a Kingdom or Monarchy." Dr. Schoolcraft wrote: "From _Ojibwai_ (Chippeway) is formed _Ojib-wain-ong,_ 'Place of the Chippeways;' _Monominikaun-ing,_ 'In the place of wild rice,'" Dr. Brinton wrote "_Walum-ink,_ 'The place of paint.'" The letter _s,_ preceding the locative, changes the meaning of
