Cocoon
noun / verb /kəˈkuːn/ — A silky protective case; a warm, enclosed, safe space.
Definition
A silky case spun by the larvae of many insects for protection during the pupal stage. Metaphorically: any warm, safe, and enclosed space that offers protection and comfort. To cocoon is to envelop in something protective.
Beyond the definition
We cocoon when we need to be safe. The impulse — to wrap, to enclose, to reduce the world to a manageable size — is as biological as the insect's silk. Sometimes the cocoon is necessary. Sometimes it becomes a habit.
Origin & history
French: 'cocon', from Provençal 'coucoun', from 'coque' (shell). Related to 'coque' (eggshell). The metaphorical use of cocoon as a warm, enclosed safe space developed in the 20th century.
