What is a lexicon?
A lexicon is a structured, machine-usable repository of relevant linguistic knowledge about words in a language. A lexicon will contain historical variants (orthographical variants, inflected forms) and link them to a corresponding dictionary form in modern spelling (known as a ‘modern lemma’). In this way, a user can search for a modern word (‘water’) and receive results that take into account all historical variants in that language (‘wæter’, ‘weter’, ‘waterr’, ‘watre’, etc.)
