hindrance
obstacle / impediment / obstruction / delay
Noun
This term describes an obstacle that creates friction or delay, often implying a slowing down of progress rather than a complete stop. It carries a negative connotation of inefficiency or frustration, typically used in professional, legal, or logistical contexts to describe systemic or physical barriers. While it can refer to a physical object blocking a path, it is frequently used to describe abstract impediments like bureaucracy, lack of funding, or restrictive laws. It differs from a total block by suggesting that the goal is still attainable, though the process has become more arduous.
