A chain or ring for holding keys together, often with decorative attachments or practical tools.
Compound word from 'key' (Old English 'cæg') and 'chain' (Old French 'chaeine'). Developed as locks became more common and people needed to carry multiple keys.
The humble keychain represents our relationship with security and identity - these small objects often carry our most personal markers, from house keys to gym memberships, making them tiny autobiographies of our daily lives.
