The last century has seen a huge increase in the quantity of law that is written out explicitly in statutes [1], rather than being worked out on a case-by-case basis according to the common law method. This is an attempt to “improve the language” as you have suggested, but it has not made the law easier to comprehend. Detailed statutes make it harder for lawyers to build up a coherent picture of the entire legal system, because there’s a much greater risk that a solid argument based on general principles collapses due to a specific statute that the lawyer has never heard of.
