This black-line drawing of the compound glyph for the personal name Acachinan ("Reed-Chinampa," attested here as a man’s name) shows a square that is probably a fence panel, a [chinam(itl)]. It is filled with a mesh that is criss-crossing canes or reeds [aca(tl)], something like bamboo or carrizo, a type of cane in Mexico. These reeds are at an angle, and they are segmented.
The reed construction is likely in place to reinforce the sides of an agricultural plot that is made from dredging mud from canals and piling it up.
