- /səˈsteɪn/
Description
- keep going
- support
- last through
- suffer harm
- uphold
To sustain something means to keep it going over time, like keeping a conversation going, keeping life going with food and water, or holding a steady pace during exercise. Think of a marathon runner; they need strong focus to sustain their effort for the whole race. At its core, the word is about giving what is needed for something to continue existing or working. For example, a healthy ecosystem needs balanced conditions to sustain itself.
The word also means "to suffer" or "to experience" something unpleasant, such as "She sustained heavy losses in the stock market" or "He sustained an injury." It can also mean "to uphold," as when a judge sustains an objection in court. Whether you are keeping a flame alive or getting through a difficult season, the idea is the same: support, continuation, or bearing something difficult.
The word "sustain" carries a sense of ongoing support. It often means to actively help something continue to exist or work well over time. Imagine a farmer carefully tending crops; they are working to sustain the harvest by providing water, nutrients, and protection. This is the most common use: to keep something going, maintain it, or provide what it needs. A charity, for example, may rely on monthly donations to sustain its essential programs.
However, "sustain" also has another important meaning: to undergo or suffer something harmful. When we say, "He sustained a broken leg during the accident," it means he suffered that injury. This sense is related to an older idea of bearing or carrying something. In a legal context, the meaning moves closer to "uphold." If a judge sustains an objection, the judge agrees with it and allows it.
In modern environmental discussions, "sustain" is also the root of "sustainable," which refers to practices that can continue without using up natural resources. A sustainable practice lets resources recover so future generations can benefit too. That is why people talk about sustainable energy, farming, and development.
Whether you are talking about keeping a business afloat, suffering an injury, supporting an argument in court, or protecting the environment, "sustain" is a word about continuation, support, and endurance. It points to the idea that something does not simply begin, but is carried forward or held up over time.
