What does composite mean?
A composite is anything formed by combining two or more distinct parts into a single whole. The word functions as both noun and adjective: engineers speak of composite materials — such as carbon fibre set in resin — that marry the strengths of their components, while police artists produce composites by assembling facial features drawn from witness descriptions. In everyday and formal writing alike, calling something composite signals that it is not uniform but deliberately assembled: a composite score averages several measures, a composite photograph merges multiple exposures. Derived from Latin componere, "to put together," it belongs to the same family as compose and component. Its connotations are practical and technical rather than emotional, making it a precise choice whenever you want to stress that a whole has been engineered from diverse parts rather than arising naturally.
Something composed of distinct parts; especially a structural material made by combining different constituents, or an image assembled from several sources.
"The tennis racket frame is a composite of graphite and fibreglass."
In engineering, "composite" almost always means a fibre-and-matrix material unless stated otherwise.
Made up of several separate parts or elements; formed by combination.
"The committee issued a composite report drawing on data from all five agencies."
Standard regular plural; commonly used for materials and for assembled images or scores.
"Carbon-fibre composites are lighter than aluminium but just as strong."
Modern airliners like the Boeing 787 are over 50% composite by weight — the same word once described portraits stitched together from witnesses' memories.

Etymology of composite
"Composite" comes from the Latin compositus, the past participle of componere, meaning "to put together." It entered English in the early 17th century, first used adjectivally before developing its noun sense for things built from combined parts. It shares this Latin root with compose, composition, component, and deposit (from the related ponere, "to place"), which explains why all these words carry the idea of arranging or placing parts.
