IPA: /ʌnˈbrɪdʒd/
KK: /ʌnˈbrɪdʒd/
Describing something that is not connected or linked by a bridge or similar structure.
The unbridged section of the river made it difficult for the villagers to cross.
Unbridged → It is formed from "un-" (meaning not) and "bridged" (from the root "bridge" which comes from Old English "brycg", meaning a structure built to span a physical obstacle). The word "unbridged" means not having a bridge or connection over an obstacle.
Think of 'not' ('un-') having a 'bridge' ('brycg') to cross over something — that's why unbridged means there is no bridge.
