·     This glyph somewhat resembles pu. (and hence also an upside-down CHAN = “sky”).

·     As with pu:

o It has a horizontal line, dividing the boulder outline into a top and bottom half.

o The middle of the top half has a lipped-U (upside down), with “blades of grass” growing downwards.

o The top and sides of the top half have a U-shaped line of touching dots (an upside-down U in this case).

o In the middle of the horizontal line, on the upper side, there are two or three touching dots.

In these respects, pu and TAP both resemble an upside-down CHAN = “sky”.

·     The difference between pu and TAP is in the lower half, where pu has an upside down vault (= bold walls and ceiling) with two pillars between the vault and the horizontal dividing line (making it, in this respect, also exactly like an upside down CHAN = “sky”), TAP has 2 or 3 small, thin, “leaf-like” elements going from the floor to the horizontal dividing line – this being the main aspect where it differs from pu. This is hence also the main feature which distinguishes it from an upside-down CHAN = “sky”).

·     MHD is the only source I have seen which gives this as a logogram TAP = “decorate”.
