As opposed to polysemic terms, which involve the same words being applied to different concepts, homographs are words that are derived from different etymological origins. Homograph is most likely to occur as a pointer to the entry for the other instance or instances where the word is used in association with a different concept. A homograph number is a sequential number used to distinguish homographs. Although many print dictionaries use superscripts for homograph numbers, this convention has been infrequently facilitated in traditional databases. It is easily achieved in Graphical User Interfaces (GUI applications).
