solvent

Imagine you're making lemonade. Water is not just sitting there. It dissolves the sugar and lemon juice and turns them into a smooth drink. In that moment, the water is acting as a *solvent*. A solvent is a substance, usually a liquid, that dissolves another substance to make a solution. You see this idea in everyday life when nail polish remover breaks down polish or when soapy water helps wash grease away. In chemistry, solvents help substances mix and help many reactions happen. The word also has a business meaning: if a person or company is "solvent," they have enough money or property to pay what they owe.

A *solvent* is a substance, usually a liquid, that dissolves another substance, called the solute, to form a solution. It is one of the basic ideas of chemistry and also something you meet in ordinary life. Water is the best-known example. It dissolves sugar in tea, salt in soup, and many other materials around us. Other common examples include rubbing alcohol, which can dissolve some oils, and acetone, which can remove nail polish. Different solvents dissolve different kinds of materials, which is why one liquid may clean a surface well while another does almost nothing.

Beyond the kitchen or classroom, solvents are important in cleaning, manufacturing, medicine, and many industrial processes because they help carry, separate, or remove materials. The word also has a second meaning in finance. A person, company, or bank is *solvent* when they can pay their debts and their finances are in sound condition. In other words, the word can describe either something that dissolves other substances or someone who is not in financial trouble. The two meanings are different, but both suggest the ability to handle what is in front of them rather than fail under pressure.
