Impassable, an adjective, refers to a condition or an obstacle that cannot be overcome, traversed, or crossed through. It denotes a state or situation where it is impossible to proceed or make progress. It is derived from the Latin word “impassabilis,” meaning "not able to be passed over."
The term is often used to describe physical conditions, such as a terrain, road, or path that is completely obstructed or inaccessible. For instance, an impassable mountain range would imply that it is impossible to cross or navigate through due to its height, steepness, or lack of safe passage points. Similarly, an impassable river pertains to a water body that cannot be crossed by conventional means, such as a bridge.
Additionally, it can be employed metaphorically to describe abstract obstacles that impede progress, such as an insurmountable challenge or an impenetrable barrier. In this sense, it suggests a lack of feasible solutions or remedies, making it impossible to proceed or find a way forward.
Overall, the term "impassable" indicates a state of being that lacks any viable means to overcome an obstruction, thereby rendering it impossible to pass through or make any progress.
That cannot be passed; not admitting a passage.

The word impassable derives from the combination of the prefix im- meaning not or opposite of, and the adjective passable, which comes from the verb to pass. The term passable originated from the Old French word passer meaning to pass. This Old French word is believed to have its roots in the Latin word passus, which signifies step or pace. Therefore, impassable essentially means not able to be passed or crossed.
