They're distinct words that say exactly what they do. They're only hard to keep straight if you haven't taken a few minutes to understand the underlying concepts (and, in a field of complex and nuanced concepts, these are hardly the most difficult). Replacing widely-used terms with new not-quite-overlapping terms turns 2 things into 4 things and is not a solution to anything.
