蜥蜴

Etymology
Dimunitive reduplication.

Noun

 * 1) lizard

Etymology
Likely a compound of +,  from the notion that the lizards live in the shade of doors, or that they live in shadow, especially when indoors, or are thought to be crawling on doors and their dark coloring can be mistaken for their shadow. Alternatively, perhaps from 疾隠 (toku kakure “quickly hiding”) or 敏駆 (tokake “nimble runner”).
