·     No glyphs given in K&H, K&L, CMC4.

·     In the iconography, the scroll shows the sound emanating from the mouth of the singer.

·     There is some doubt about the reading of what might be the “reduced” variant of the head variant (with just the scroll).

·     MHD views the simpler glyph as being the reduced variant of the glyph with the human head and assign both the 3-character code PY3. It assigns the reading of either k’ay = “to sing” or k’ayoom = “singer” to both, perhaps in the same way that a written yu-ku can be yuk = “to shake” or yuknoom = “shaker”.

·     AT-E1168-lecture14.t0:35:57: k’ay means “to sing”, and also, actually, “to do small scale sales”. So imagine a person going through a town, he says “fresh fruit, fresh fruit, fresh fruit!”. So it’s any kind of repetitive verbal act. So, like singing or saleing or auctioning – it’s called k’ay.

·     The NAR Stela 47 and M&G examples are the name of the early Kaanul ruler formerly given the nickname “Scroll Serpent”. It would appear that the human head gets lost in the conflation with a snake head, so this is now <K’AY{oom}+CHAN> è K’ayoom Chan perhaps = “Singer/Singing/Chanting Serpent”; i.e. the old nickname can be given up, as the name can now be read.
