## Etymology
From Middle English Lucy, from Old French Lucie (notably after the Christian martyr Lucia of Syracuse), from Latin Lucia (feminine of Lucius, a Roman praenomen), from lux (“light”).
The name of the Australopithecus skeleton came from the Beatles song “Lucy in the Sky with Diamonds”, which was being played repeatedly at the dig site camp at the time of the discovery. The slang term for LSD also derives from the song name, which many believe is essentially a reference to the drug.
