In any PIE root (lets say Reconstruction:Proto-Indo-European/ten-) there are sometimes terms derived with the correspondent explanation (innovative of, stative, -grade) but there are others that are just given as an extension (with hyphen), like -onts, -os/-es, -tis, -tlo, -tus, -s-li, -eh2, -tós. Shouldn't this extensions already exist and then be linked (for example, the Reconstruction:Proto-Indo-European/-tós of *tn̥-tós if it's the case) or be explained like that "suffix denoting extent of time)"? I mean, is there an official repertoire of those extensions/suppletions applied before the suffix?
