Full Idea
I am persuaded that common speech is full of vagueness and inaccuracy, and that any attempt to be precise and accurate requires modification of common speech both as regards vocabulary and as regards syntax.
Gist of Idea
Common speech is vague; its vocabulary and syntax must be modified, for precision
