Pathbreaking → It is formed from "path" (from Old English "pæth", meaning a way or track) and "breaking" (from "break" which comes from Old English "brecan", meaning to separate or shatter). The word "pathbreaking" refers to the act of creating a new path or making significant changes that lead to new developments.
Think of a 'path' as a way and 'breaking' as creating a new direction — that's why pathbreaking means making a new way forward.
