General definition of "canonical

I often use the word "canonical", especially in serious or specialized discussions. But what does it really mean? Well, in its simplest sense, "canonical" means "conforming to a rule", or "officially recognized". It's a word that can be found in many different contexts, but which always retains the idea of a standard, a model to be followed.

Whether used to describe a sacred text, a vocabulary word or a mathematical formula, this term is used to designate what is considered valid, fundamental, even indisputable. Personally, I find it elegant and useful, as it imposes intellectual rigor on our exchanges.
