Pronunciation: [stˈɒps ˈʌp] (IPA) 
The spelling of "stops up" may seem confusing as it combines three consonant sounds at the end. However, it follows standard English spelling rules by using the letter "s" to represent the "s" sound, the "p" to represent the "p" sound, and the letter "s" again to represent the "z" sound due to voicing after the consonantal plosion. The correct pronunciation of "stops up" is /stɒps ʌp/. It means to block or seal a passage or opening.
"Stops up" is a verb phrase that refers to the act of blocking or obstructing a passageway or a container. When something stops up, it becomes blocked or clogged, preventing the smooth flow or movement of substances, such as air, liquid, or even solid objects.
In a literal sense, "stops up" commonly describes the obstruction of pipes, drains, or other plumbing systems due to the accumulation of debris, such as food particles, hair, or other foreign objects. Consequently, the clog impedes the normal and efficient functioning of the plumbing system, causing a decrease or complete halt in the flow of water or sewage.
Additionally, "stops up" can be figuratively used to depict the hindrance or impeding of progress, communication, or any process that is meant to flow seamlessly. For instance, the phrase can describe a congested road blocking the movement of vehicles, an overloaded or congested network causing slow internet access, or even an individual's inability to express themselves adequately, leading to a breakdown in communication.
Overall, "stops up" encompasses the idea of hindrance, interruption, or blockage, whether it pertains to the physical obstruction of a passage or the interference with an ongoing process or event, highlighting the consequential disruption and impeded flow.
The word "stops up" is a phrasal verb and doesn't possess etymology of its own. Instead, we can look at the individual words "stop" and "up" to understand their origins.
"Stop" originated from the Old English word "stoppian", which meant to close or block an opening. It can be traced back to the Proto-Germanic word "stuppōną". The word "stop" has remained relatively unchanged over the centuries, both in terms of form and meaning.
"Up" is a preposition that has a variety of meanings, including indicating a higher position, completion, or direction. It stemmed from the Old English word "ūp", which had the same meaning. The Proto-Germanic word "ūp" also contributed to its development.
When combined, "stops up" simply denotes the act of blocking or closing something, often referring to an opening or passage.
