·    Do not confuse this with the semantically related wak and kamis, which are two other words for “centipede”.

·    The full-figure variant, from Altar O' / Monument 23:

o Shows a human-like body with the head of a centipede, identified by the two characteristic fangs.

o Is quite rare, in this case infixed in the ISIG to match the HAAB-month of the ISIG’s LC.

·    The mouth is usually open, but in some cases, it can be closed (when the mouth is closed, it might be confused with the “CHAPAAT-variant” of BAAK).

·    Diagnostics to help distinguish it from the “CHAPAAT-variant” of BAAK are:

o CHAPAAT often has a “scroll” within the top part of the head (which BAAK never has).

o CHAPAAT often has a forehead ornament (especially if the mouth is closed) Note: the “CHAPAAT-variant” of BAAK also sometimes has a forehead ornament!

·    Do not confuse this with the visually similar (perhaps uncommon variant of) CHAN = “snake” with an open mouth (see CHAN = “snake”).

·    Martin-GBoLMotMC.t0:13:00 also gives Kettunen&Davis-SCSC.p33.tab1.2 without giving the source; Martin states that this is the one instance from which we know that the logogram for a centipede is pronounced chapaat, but Kettunen&Davis-SCSC.p33.tab1.4 shows another, and EB.p48..pdfp53 #3 lists cha?-pa-tu > chapat RAZ Tomb 19 Vessel, which is probably the same reference as Kettunen&Davis-SCSC.p33.tab1.4.

·    The drift of Martin’s assertion is still important: there are preciously few sources from which we can surmise that the central consonant is ‑p‑; however, Ch’olti’, Ch’orti’, Yucatec and Mopan all have clearly related cognates, with ch‑p‑t (Kettunen&Davis-SCSC.p26-27).
