Yet another hyphotesis: while our corpus is small and most of the words I am using for this hypothesis seem to be related (“water”, “sea”…), there is a strong tendency for the glyph ᓄ to be found only at the end of words (mostly nouns).

The exception is ᘝᓄᘈᖉᐣ, a somewhat unusual word that many suppose is the name of the Beanie city. Maybe its name is actually a compund word, ᘝᓄ and ᘈᖉᐣ? An even wilder guess: ᘝᓄ or, more likely given the syntax, ᘈᖉᐣ could mean “new” (as in “New York”).
