I know it was coined in the 15th century, that's all I could find. It comes from the latin contextus meaning woven together, so perhaps it began in french first. But I want to know who originally invented the idea of context, what was the first example of writing we have of it? Who coined it? Does Martin Luther use this concept, (it might be in the form of Aufhebung)? Specifically I am looking for an example where someone directly states that the meaning of a word can be changed by its proximity to surrounding passages. Not necessarily as direct or unequivocal as a statement that "a word can only mean one thing at a time".
