Homonym: base (Foundation)
A "base" is a fundamental part of something that supports or underlies it. In science, for example, a base can refer to a substance that can accept protons or donate electron pairs in chemical reactions. Common bases include substances like sodium hydroxide and ammonia, which are used in various applications, from cleaning products to manufacturing.
In everyday language, a base can also mean the bottom part of an object, like the base of a lamp or a building. This base provides stability and strength, ensuring that the object stands firm. Without a solid base, many structures, like houses or trees, would not be able to stand tall.
