Troughs, in various contexts, can refer to different meanings. Here are two key definitions of troughs:
1. In the context of geography and landforms, a trough is a long and narrow depression or valley. It typically forms between two parallel ridges or mountain ranges, elongated in shape. Troughs can be created through various geological processes, such as erosion by rivers or glaciers, faulting, or even tectonic plate movement. These landforms have a low-lying profile, often with relatively flat bottoms, delimited by higher elevated features on both sides. Troughs are commonly found in mountainous areas, forming natural corridors for the flow of rivers or as basins for glaciers.
2. In the field of economics, specifically relating to business cycles, a trough represents the lowest point of a recession or economic downturn. It is the stage of the business cycle that marks the end of declining economic activity before the start of a recovery or expansion phase. This phase is characterized by reduced consumer spending, limited business investments, rising unemployment rates, and stagnating production levels. Troughs are considered the opposite of peaks, which represent the highest point of economic activity. They are important indicators for economists in analyzing the health and trajectory of an economy, helping to identify turning points and predict potential recoveries.

The word "troughs" originates from the Old English word "trōh", which can be traced back to the Proto-Germanic word "trōgaz". This Proto-Germanic word is believed to have its roots in the Proto-Indo-European base "*derk-" or "*tere-", which means "to cut or bore". Over time, the word "trōh" evolved into "troughs" in modern English, referring to long, narrow containers, often made of wood or stone, used for holding water or animal feed.
