Tangentially, English is the most agile language of all; words can and do bleed into different categories all the time. My favorite is when people say they've "third-class'd" a route -- meaning that they climbed it without a rope.
Yeah thats kind of like how I view different things in English too. For example, when people are still confused between their/there or they're. A lot of people tend to blend all the 3 together . Call be a obnoxious but thats a pet peeve of mine
