Definition: "Synthetite" is the word for "synthetic." Synthetica is a chemical compound formed from organic substances like sugars, alcohols or synthetic materials by a reaction with certain catalysts and heat. Synthese refers to taking a substance that has been in existence since prehistory and adding some kind of chemical process to it in order to make something new or improve the original substance. Synthetica is often used in science to describe the synthesis of compounds from simpler substances, as well as the process by which materials are altered in order to achieve desired properties. Synthesizing a substance like wood into paper requires a series of reactions that involve specific steps like mixing, stirring and heating.
