"Three principals results have forcibly struck my mind... They are the following:

1. That the American languages in general are rich in grammatical forms, and that in their complicated construction construction, the greatest order, method and regularity prevail

2. That these complicated forms, which I call polysynthesis, appear to exist in all those languages, from Greenland to Cape Horn.

3. That these forms appear to differ essentially from those of the ancient and modern languages of the old hemisphere." (Duponceau 1819:xxii-xxiii)

"The manner in which words are compounded in that particular mode of speech, the great number and variety of ideas which it has the power of expressing in one single word; particularly by means of the verbs; all these stamp its character for abundance, strength, and comprehensiveness of expression, in such a manner, that those accidents must be considered as included in the general descriptive term polysynthetic." (Duponceau 1819:xxvii)

"I have explained elsewhere what I mean by a polysynthetic or syntactic construction of language.... It is that in which the greatest number of ideas are comprised in the least number of words. This is done principally in two ways. 1. By a mode of compounding locutions which is not confined to joining two words together, as in the Greek, or varying the inflection or termination of a radical word as in the most European languages, but by interweaving together the most significant sounds or syllables of each simple word, so as to form a compound that will awaken in the mind at once all the ideas singly expressed by the words from which they are taken. 2. By an analogous combination of various parts of speech, particularly by means of the verb, so that its various forms and inflections will express not only the principal action, but the greatest possible number of the moral ideas and physical objects connected with it, and will combine itself to the greatest extent with those conceptions which are the subject of other parts of speech, and in other languages require to be expressed by separate and distinct words.... Their most remarkable external appearance is that of long polysyllabic words, which being compounded in the manner I have stated, express much at once." (Duponceau 1819:xxx-xxxi)

Languages with a high degree of synthesis but without being incorporating include Central Siberian Yupik and Western Greenlandic.

An example from Western Greenlandic, a polysynthetic and agglutinating (but not incorporating) language (Fortescue 1983:97; cited in Evans and Sasse 2002):
