The term 'of several parts' can be described as a COMPOSITE, which is a nine-letter word. A COMPOSITE is an object or structure made up of multiple parts or components that are combined together to form a single entity. This term is often used to describe a complex system or structure that is composed of many different elements. For example, a car is a COMPOSITE of many different parts such as the engine, transmission, and body. Similarly, a computer is a COMPOSITE of many different components such as the processor, memory, and storage.
