I think your statement sounds controversial but I’d be willing to argue that. I.e the opposite of formal is indeed intuitive. I’d start like this : if you’re explaining something in English then you’re invoking and reliant on the readers common sense and intuition to do the work in your explanation. E.g a pipe is used to smoke tobacco. Pipe. Usage. Smoking. Tobacco. It’s left to the reader to define, disambiguate and on that basis accept. Contrast to: a pipe is used for transporting water.
