Is there a reason why the English language has “special” words for a specific topic, like related to court (plaintiff, defendant, warrant, litigation), elections/voting (snap election, casting a ballot)?
And in other cases seems lazy, like firefighter, firetruck, homelessness (my favorite), mother-in-law, newspaper.
Most often the “fancier” words are loanwords from other language. Plaintiff/Defendant are from the French “pleintif/defendant”, litigation is from Latin. Firefighter, firetruck, and other compound words were created relatively recently compared to the others. Firefighters, firetrucks and newspapers mostly didn’t exist until after English mixed with other languages.
Also, the number of loanwords in English is completely absurd. Some other languages resisted borrowing/stealing special terminology from other languages by coming to with their own clever new words.
For example, entrepreneur is a clear loan from French where a salesman is a simple and clear description of a man who sells something. If you don’t know French, you’ll have no idea what the word entrepreneur means, but if you know basic English, salesman should be crystal clear to you.
Many other languages developed lots of these types of clear words in order to make communication easier and less elitist. English is completely wild and there’s no central authority that could reasonably give any recommendations that anyone would listen. This sorts of uncontrolled wild growth and stealing has been going on for centuries, and now we’ve ended up with a complete train wreck of a language.
And that’s just the tip of the iceberg! Wait until you hear about the history behind how spelling and pronunciation became the disaster we have today.
A lot of them haven’t changed much in the last few centuries either. Law is a pretty arcane thing. I also suspect they don’t want most people to understand it too well. If the legal system is a confusing, overcomplicated, bureaucratic nightmare, then the lawyers will always have job security and charge stupidly high rates for their work.
