Metamorphosis
noun /ˌmet.əˈmɔː.fə.sɪs/ — A complete, profound transformation of form, nature, or character
Definition
A fundamental and complete change in form, nature, or character — as in the biological transformation of a caterpillar into a butterfly, or the profound shifts of self that mark a human life.
Beyond the definition
Change that goes all the way. Metamorphosis is not improvement or development — it is a change so complete that what comes out is not recognisably the same as what went in. The caterpillar does not become a better caterpillar. It becomes something else entirely.
Origin & history
From Greek 'metamorphosis' (transformation) — 'meta-' (after, beyond) + 'morphe' (form). Used by Ovid as the title of his great mythological poem cataloguing the transformations of gods and humans. The word has carried the weight of radical change ever since.
