"Are composed of" is a phrasal verb used to describe the elements or substances that make up a particular entity, structure, or object. This phrase indicates the composition, constitution, or constituents of something.
When we say that something is composed of certain components, it implies that those components are combined or brought together to form a whole. This phrase highlights the idea that the entity or object is not a single homogeneous unit, but rather a collection of different elements that work together to create a desired outcome.
For example, when we say that a painting is composed of various colors, it means that those colors are combined to create the final image. Similarly, we might say that a building is composed of bricks, cement, steel, and glass, denoting the materials used in its construction. This phrase can also refer to abstract concepts, such as when we say that a melody is composed of specific musical notes or that a sentence is composed of words and punctuation marks.
In summary, "are composed of" suggests the combination or presence of various constituents or elements that, when brought together, form a larger whole. It underscores the notion that something is not a single entity but rather a composition of different parts, providing an understanding of the inherent components that contribute to its existence and functionality.
