Which term means 'made up of various components'?

The term "composite" precisely refers to something that is made up of various components or elements. In various contexts, a composite can signify a material or object that is constructed from different substances to create a product with enhanced properties or characteristics. For instance, composite materials in engineering and construction combine two or more distinct materials to achieve improved strength or durability. This definition aligns perfectly with the idea of consisting of diverse parts.

In contrast, "didactic" pertains to teaching or instructive qualities, particularly in a way that is intended to educate or inform. "Ephemeral" means something that is transient, fleeting, or short-lived, emphasizing brevity rather than composition. The term "continuum" refers to a continuous sequence or range where items gradually transition from one state to another, without distinct boundaries. None of these terms shares the connotation of being made up of various components, further solidifying "composite" as the correct choice.
