Lexicon

What is a lexicon? The alphabetical arrangement of the vocabulary associated with this pathfinder. The purpose of articulating the vocabulary in context is defined in the Merriam-Webster dictionary as a “weaving together of words, the parts of a discourse that surround a word or passage and can throw light on its meaning; and the interrelated conditions in which something exists or occurs." These are the terms I need to understand and define in order to set the context of my research.
