By a 'fusional-agglutinative' language we would understand one that fuses its derivational elements but allows a greater independence to those that indicate relations.
- Sapir (1921), Pag. 140

There are [...] a large number of languages that fuse radical element and affix in as complete and intricate a fashion as one could hope to find anywhere without thereby giving signs of that particular kind of formalism that marks off such languages as Latin and Greek as inflective.
- Sapir (1921), Pag. 129

Instructive forms may be cited from Nootka.[...] The nominalizing '-i' and the indicative '-ma' are not fused form-affixes, they are simply additions of formal import.
- Sapir (1921), Pag. 133

As far as Latin and Greek are concerned, their inflection consists essentially of the fusing of elements that express logically impure relational concepts with radical elements and with elements expressing derivational concepts.
- Sapir (1921), Pag. 135

In an 'agglutinative-fusional' language the derivational elements are agglutinated, perhaps in the form of prefixes, while the relational elements [...] are fused with the radical element, possibly as another set of prefixes following the first set or in the form of suffixes or as part prefixes and part suffixes.
