- Feeding Container: A trough is a long, narrow container from which animals eat or drink.
- Geological Formation: It can refer to a long, narrow depression in the ground, especially one that is natural.
- Wave Motion: In physics or oceanography, a trough is the lowest point of a wave between two crests.
Figurative Uses of Trough
In a more figurative or symbolic sense, ‘trough’ is often used to indicate a period of decline or stagnation, especially in graphs or economic trends. Here are a few examples:

- Experiencing repeated hardships without relief.
- Observing a pattern of consistent decline in data or emotions.
- Describing physical formations like valleys or ocean currents where multiple troughs occur sequentially.
Grammatical Function
Grammatically, the repetition in trough and trough creates an effect similar to expressions like ebb and ebb or loss and loss. This type of repetition is used for poetic emphasis, creating a rhythm or stressing the continuous nature of a concept. It might not be commonly found in academic texts, but it can appear in narrative writing, speeches, or artistic descriptions.
Examples in Context
Scientific Usage
In scientific descriptions, particularly in physics or oceanography, the term trough and trough can be used when analyzing wave patterns. For instance:
‘The measurement between trough and trough was used to determine the wavelength in this water wave experiment.’
This usage focuses on the distance between successive low points in a wave pattern and provides a measurable, observable context.
Economic or Business Usage
In economics, the idea of going from trough to trough rather than peak to trough suggests prolonged or repeated recession phases. For example:
‘The company’s performance remained in a state of trough and trough, never quite rising into profitability.’
Such usage emphasizes a lack of recovery or upward momentum over time.

- Peak and trough: Indicates normal fluctuation or variation.
- Trough and trough: Suggests persistent lows or a lack of progress.
Crest and Trough
In physics, especially in wave theory, ‘crest and trough’ are technical opposites the crest being the highest point, and the trough the lowest. A sentence such as:
‘The amplitude was calculated between the crest and trough of each wave.’
This demonstrates that both are essential to understanding a wave’s motion, balance, and dynamics.
Origin and Etymology of Trough
Historical Background
The word trough traces its origin to Old English troh, which referred to a wooden vessel or container. Over centuries, its meaning expanded to describe low areas in physical and metaphorical senses. The repetition in trough and trough as a stylistic or descriptive device likely stems from poetic or artistic traditions rather than formal grammar rules.
