Chrysalis

Part of speech: noun

Pronunciation: /ˈkɹɪsəlɪs/

Definitions

1. A stage in the life cycle of specific insects where a larval form undergoes metamorphosis within a protective shell or casing that aids development into the adult form
2. The transformation phase for certain insects occurs inside a protective covering, allowing the larvae to develop and emerge as adults in a structured environment
3. A developmental stage of certain insects that occurs within a protective casing, enabling larvae to metamorphose into their adult forms as they undergo significant changes

Etymology: The chrysalis is named for gold, though the link is not obvious from the insect's appearance. Its ancient Greek ancestor, "khrusallís," is built from "khrusós," meaning gold or golden, and it was applied to the pupal case of an insect, probably because some of these casings are glossy and metallic. The Greek word then passed into Latin as "chrysallis," and English took it from there, so the word carries a gleam of gold inside the drab shell of a caterpillar. The Greek ending is less transparent. The "-allís" part is usually treated as a feminine suffix, but the word is unusual: similar-looking Greek words such as "thruallís" and "aruballís" seem to come from a language spoken in the Greek region before Greek arrived, so the full ancestry of the ending is uncertain. What is clear is that the gold in the name points to the surface sheen of the casing rather than to anything in the insect itself.
