·    No glyphs given in K&L, BMM9.

·    There are various pronunciations given for “12”: lajcha’, lajchan, lajuncha’, lajunchan.

o Despite the fact that many epigraphers have a long-u in juun and lajuun, the transliteration/transcription lajuun- in connection with “12” seems to be particularly uncommon – just the short-u is used.

o The only hit on Google I managed to find is in Tsukamoto&Olguín-TSaA.p194.para1.l-9 (only available as extract from Google Books, typography slightly adjusted): The upper left corner of Lintel 26 of Yaxchilan depicts ti-12-? CHUM-KAN-JAL-wa T’AB-yi yu-xu?-lu KAWIIL?-CHAAK? AJ-SAK-o-ka, ti lajuunchan ... chum kanjalaw t’ab[aa]y yuxul? k’awiil? chaak? aj sak[h] o’[o]k(?), “on the day 12 Eb and 0 Pop (February 8, 724 CE), this lintel is carved by K’awiil Chaak?, he of the White Valley”, which probably means he is from El Palmar.

o 25EMC.pdfp4.#2 is given as LAHCHA’ but this is probably a typo (or rather a failure to upgrade from an earlier reading) – elsewhere in 25EMC, “12” is given as LAJUNCHA’ / LAJUNCHAN.

·    TOK.p24.r1.c2 gives only “12”, but lajcha’ given in AT-E1168-lecture6.t0:39:45 (in connection with the bar-and-dot notation).

·    This glyph is basically the animated variant of CHAN = “sky”.

·    AT-E1168-lecture6.t0:50:11: “11” and “12” are a total mystery, “2” is a total mystery; as far as I know [in terms of the reason for their particular god-head variants].

·    Sim: it makes some sense to me that “11” and “12” have special head glyphs which happen to be animated forms of “earth” and “sky”. In English, “eleven” and “twelve” are (etymologically speaking) derived from words which meant “one left (over)” and “two left (over)”, the -v- in both words being a remnant of the -f- in “left” or the -v- in “leave”. That is to say, there’s “one (or two) left over, after 10”. Similarly, in Classic Maya, after “death” at “10”, there’s the “earth” and the “sky” left over, for “11” and “12”!

·    Overall usage statistics for “12” (2025-09-07) – total number of times “12” is written in the MHD corpus is 724 = 703 + 21:

o Bar-and-dot (“blcodes contains 012”): 703 hits (703/724 = 97.10%).

o CHAN-based head (“blcodes contains PL6”): 21 hits (21/724 = 2.9%).

The fact that the head variants are used as little as 3% of the total number of times “12” is written is perhaps not surprising. This is about the same percentage as with “11” (see previous entry).
