219 LEXICOGRAPHER

In some of the situations of our work we find ourselves in the dual role of 'native language user' and 'lexicographer'. The difference is that the language user is often unaware of his assumptions concerning usage, meaning, syntax, etc. : they are implicit or tacit knowledge. Part of the responsibilities of the lexicographer is to make those implicit rules of grammar, usage, etc. , explicit.
