tzintli (Mdz30r)
This element for rear end or buttocks (tzintli) has been carved from the compound sign for the place name, Tollantzinco. In that compound it was a phonogram, but here we are including it as a logogram. It is the lower half of a man's body (indicated by the white belt of the loincloth). He is somewhat horizontal, in profile, facing toward the viewer's right. His skin is terracotta in color.

As with all—or at least the vast majority—of examples of this glyph, the meaning "buttocks" has nothing to do with the meaning of the glyphs, although it may have a metaphorical value of "lower." When modifying a place name, as Frances Karttunen suggests, the meaning of "tzin" is new, little, or lower. It can also refer to something revered, for instance, when combined with something having the element "teo" (from teotl, divine force).
