Literary notes about Obstruction (AI summary)
In literature, "obstruction" functions both as a depiction of physical barriers and a metaphor for abstract challenges. Authors may use the term to describe natural impediments that alter the course of rivers or halt progress, as seen when a river is choked by a blockage that causes high floods [1] or when a rushing current washes away a barrier [2]. At the same time, the word is employed in more technical and symbolic contexts—such as in phonetics where it defines the cessation of airflow in producing certain sounds [3] or to evoke internal or social blockages that characters must overcome [4] and that serve as both puzzles and motivations [5]. This dual usage enriches narratives, allowing "obstruction" to represent obstacles that are simultaneously tangible and emblematic of broader struggles.
