User blog comment:ChishioKunrin/Reminder: Weiss' Semblance is Glyphs, Not Ice/@comment-17099359-20141128203442/@comment-10380701-20141129010540

I just assume the simple thing.

Glyph is pretty much a catch-all term for a category of semblance that involves the usage of runic thingies. Similar to how Sun and Blake both have clone-type semblances.
