Etymology

Origin of chain

First recorded in 1250–1300; Middle English chayne, from Old French chaeine, from Latin catēna “fetter”; see catena

Explanation

A chain is a long series of connected metal links. Chains are strong and flexible, so they're useful for pulling a heavy load or securing a dangerous animal. The chain that anchors a ship to a dock or secures a warehouse door is just a larger version of the gold chain you wear around your neck — both are made of loops of metal. More figurative types of chains include things that hold you back, like the chains of your responsibility to your family, or connected occurrences — like a chain of events that leads to you meeting your best friend.
