Does anyone have a reference for how the "-que" suffix might be analyzed in a parse tree? I want to know because knowing the parse tree usually helps me internalize the grammar. I'm having trouble with "-que" because it seems illogical to place "-que", which is essentially a conjunction, one token into the second phrase.
My text books only give a basic description of "-que" and some similar usage examples. Interestingly, Wiktionary says that there was a PIE and Proto Germanic suffix along the same lines, but I don't know where to research that more either.
