IPA: /ˈlɒɡdʒæm/
KK: /ˈlɔgˌdʒæm/
A situation where progress is blocked or delayed, often due to a large number of things being stuck together, like logs in a river.
The negotiations reached a logjam, preventing any agreement from being made.
Logjam → The word is a compound of "log" (from Old English "logg", meaning a piece of wood) and "jam" (from Middle English "jamme", meaning to press or squeeze). A logjam refers to a situation where logs are stuck together, preventing movement, and metaphorically describes any situation where progress is blocked.
Picture logs ('log') that are 'pressed together' ('jam') and stuck, which helps you remember that a logjam is a blockage that prevents progress.
