The "-m" suffix is one of the most puzzling verbal affixes in the language. Some argue that it has varying uses of its morpheme, or that the suffix itself represents different morphemes due to the transitive bases the suffix consists of. The plural of the "-m" suffix has no known cognates. Another suffix is "-uks". This suffix was never recorded, and there is skepticism about its derivatives. Some say that, because of the "-uks" suffix, Bella Coola influenced the Wakashan and Athapaskan languages, also originating from the British Columbian coast. Others believe, though, that the "-uks" suffix used in the Bella Coola language were previously recorded in the Chinook Jargon, thus it was taken from that language. At this point in time, linguists have two stances on this argument: either "-uks" did originate from the Chinook jargon, or "-uks" is one of the few elements originating from languages spoken south of the Salishan area of the British Columbia coast, which is difficult to decipher due to the lack of recorded evidence on it. Linguists are unsure what this meaning could bring. An opinion sometimes considered is that people of all the mentioned languages, from Chinook to Bella Coola to Wakashan/Athapaskan, were somehow congregated, and its people were, for more than a brief amount of time, associated with one another. This could have derived from intertribal marriages, which meshed the different structural components of the language to form one unique, syntactical language structure. We cannot testify to this hypothesis, though, due to the lack of archives previously produced/left behind by the people that once spoke these languages fluently.
