Derivation of the botanical name:

Oxalis, Greek oxys, acid, sour, sharp; referring to the taste of the leaves and the stem; Pliny used Latin oxalis, idis, for some species of Rumex.

pescaprae, pes, foot; capra, goat; foot of the goat, alluding to the shape of the leaflet.
The Hebrew name: חמציץ, hamzitz, coined from חמץ (with reduplication of the צ) on the analogy of the name Oxalis, which derives from Latin oxalis (= a sort of sorrel).
