Much of AutoMathic's vocabulary is stored in external data files. However, some of its linguistic knowledge is embedded in the program itself. In most cases, language was embedded when the meaning of a common word could not be determined with a simple, context-free translation driven by its data files. Below are some tables of special input forms that are handled by AutoMathic's embedded translations:
