chrysalis (n.) Look up chrysalis at Dictionary.com
c.1600, from Latin chrysallis, from Greek khrysallis (genitive khrysallidos) "golden colored pupa of the butterfly," from khrysos "gold," perhaps of Semitic origin (compare Hebrew and Phoenician harutz "gold") + second element meaning something like "sheath." Seeking a plural, OED leans toward the classically correct chrysalides.
