길이 막히다.

The Korean phrase '길이 막히다' (gil-i mak-hi-da) is composed of two main parts: '길' (gil) meaning 'road' or 'path', and '막히다' (mak-hi-da) which is the passive form of '막다' (mak-da) meaning 'to block', 'to obstruct', or 'to clog'. The word '길' (gil) is an ancient Korean word with roots in Old Korean. It appears in various forms in historical texts and is a fundamental term for movement and passage. Its meaning has remained consistently tied to physical paths or routes over centuries. The verb '막다' (mak-da) also has deep roots in the Korean language. Its etymology can be traced back to Old Korean, where similar-sounding words conveyed the idea of closing, stopping, or hindering. The passive suffix '-히-' (-hi-) transforms the active verb '막다' (to block) into '막히다' (to be blocked). Therefore, '길이 막히다' literally translates to 'the road is blocked' or 'the path is obstructed'. This literal meaning naturally extends to the metaphorical sense of traffic congestion, where the flow of vehicles is hindered or stopped, making the road effectively 'blocked'. The phrase is commonly used in everyday Korean to describe situations ranging from a physical obstruction on a path (like a fallen tree) to heavy traffic on a highway. Its clear and direct construction makes it easily understandable and widely applicable in various contexts involving impedance or stoppage on a route.
