Trivial names often have their roots in the common language; in chemistry they may come from historic usages in, for example, alchemy. Many of the names pre-date the institution of formal naming conventions. Frequently, trivial names derive from some notable property of the thing being named.
Trivial names, generally, are not useful in describing the essential properties of the thing being named such as the molecular structure of a chemical compound or the phylogenetic relationships of organisms. In some cases, trivial names can be ambiguous or will carry different meanings in different industries or in different geographic regions. On the other hand, systematic names can be so convoluted and difficult to parse that the trivial name is preferred. For example, the most important structural feature of Diazonamide is that it's a nonribosomal peptide, which is denoted by the suffix "amide".
