How are carboxylic acids traditionally named using common names, and what suffix is added to these names?

Carboxylic acids are traditionally named using common names based on their source or historical significance. The suffix “-ic acid” is added to the root name of the hydrocarbon chain. For example, acetic acid (CH₃COOH) is derived from vinegar (acetum in Latin), and formic acid (HCOOH) is found in ant venom. The common names often reflect the origin or characteristic properties of the acids. This nomenclature system is widely used in simple carboxylic acids, but for systematic naming, the IUPAC (International Union of Pure and Applied Chemistry) nomenclature is preferred, providing a more standardized and precise way of naming organic compounds.
