Lacertan.

Brit.

/ləˈsəːtə/, U.S.

/ləˈsərdə/

Forms:

α. 1600s– Lacerta.

β. (In Latin genitive form) 1800s– Lacertae Brit. /ləˈsəːti/, U.S. /ləˈsərˌti/.

Origin: A borrowing from Latin. Etymon: Latin lacerta.

Etymology: < classical Latin lacerta lizard (see lacert n.¹), in post-classical Latin also in the names of iatrochemical preparations (1575 in lacerta viridis , lit. ‘green lizard’, a preparation of mercury and copper; compare sense 1) and denoting a constellation (J. Hevelius Uranographia (1687) 12).In sense 1 probably ultimately after the use of lacerta in the Paracelsian corpus alongside early modern German eydex lizard (German Eidechse : see ask n.²) to refer to lizards as used in medicine. The use of the Latin genitive form as postmodifier in star names is a practice that originated in post-classical Latin.

†1. Alchemy. green Lacerta: a green preparation containing mercury and copper, supposedly of medicinal value. Obsolete.

2. Astronomy. (The name of) a small inconspicuous constellation of the northern hemisphere, on the edge of the Milky Way between Cygnus and Andromeda; the Lizard.
