@isthmus_x The only information I could find on Wikipedia is the descriptions below, which confuse me more! 😂
'Licensure means a restricted practice or a restriction on the use of an occupational title, requiring a license. A license created under a "practice act" requires a license before performing a certain activity, such as driving a car on public roads.'
English is massively influenced by Latin, which allows for a vast variety of technical terms to be invented. They might be in the dictionary, but the absolute majority of them are never used by real humans.
I once saw a hilarious dictionary published about 200 years ago, where the author had literally attempted to invent new words for the scientific age, just jamming Latin words together to try and make sense of them. Latin is very modular like that. However, about half of his words were never used. They were just too difficult to say, or sounded ridiculous. That's what "licensure" sounds like to me.
