Synthesized

Synthesized is the past participle of synthesize and is used as an adjective to describe something produced by synthesis rather than occurring naturally or as a result of other processes. The term comes from the Greek sunthesis, meaning putting together or placing of parts.

In science and technology, synthesized objects are those created through deliberate combination of components or steps. In chemistry and materials science, synthetic compounds and polymers are produced through controlled reactions or polymerization, examples being nylon, polystyrene, and many pharmaceuticals. In biochemistry and molecular biology, synthesized proteins or nucleic acids are produced in laboratory systems or via recombinant methods, as opposed to being extracted from living organisms.

In electronics and media, synthesized refers to sounds or voices generated electronically rather than recorded from acoustic sources. Synthesized music and speech are produced by electronic synthesizers or software, and are foundational to fields such as digital audio, sound design, and text-to-speech technology.

In data processing and privacy contexts, synthesized data or synthetic data are artificially generated datasets used to train models or to test systems while protecting sensitive information. This approach helps mitigate privacy concerns and can expand coverage in machine learning workflows.

In linguistics, synthesis describes the process of forming words by combining morphemes; languages with extensive affixation or inflection are often described as synthetic. The term synthesized commonly appears in technical writing to distinguish human-made or lab-created results from those occurring in nature.
