·     This glyph is also a logogram UH = “moon”.

·     The iconographic origin of this glyph is the crescent moon, with the two points meeting at the top being the endpoints of the crescent. It’s used as the syllabogram ja but also to write the word “moon” as the logogram UH. There are no distinguishing characteristics between these two usages – it’s the “same” glyph, distinguished only by context. MHD distinguishes them with a lowercase suffix to the 3-letter MHD character code – ZU1a and ZU1s respectively:

o MHD.ZU1b: used as syllabogram ja. A search in “Classic - Blocks” on “blcodes contains UAZ1s” gives 2,750 hits.

o MHD.ZU1a: used as logogram UH. A search in “Classic - Blocks” on “blcodes contains UAZ1a” gives 63 hits.

The statistical analysis shows that the crescent moon glyph is used far more as ja than as UH.

Sub-variants (2)

·     A. Full:

o Crescent moon with the tips of the crescent curve around to almost touch, forming a “bay”.

o Sometimes tips touch and merge so that the bay becomes a totally enclosed internal circle.

o Within the bay (or circle) a diagonal row of three non-touching dots, the middle dot often slightly larger than the outer ones.

·     B. Reduced: half of full.

·     Human head with infixed three quarters of the full form – the inner edge of the crescent begins on the left at the level of the nose, not (as might be thought) at the level of the mouth.
