50 Years of Stupid Grammar Advice
The book's toxic mix of purism, atavism, and personal eccentricity is not underpinned by a proper grounding in English grammar. It is often so misguided that the authors appear not to notice their own egregious flouting of its own rules. They can't help it, because they don't know how to identify what they condemn.And so on. Interesting read that will teach you more grammar than the entire Elements of Style.
"Put statements in positive form," they stipulate, in a section that seeks to prevent "not" from being used as "a means of evasion."
"Write with nouns and verbs, not with adjectives and adverbs," they insist. (The motivation of this mysterious decree remains unclear to me.)
And then, in the very next sentence, comes a negative passive clause containing three adjectives: "The adjective hasn't been built that can pull a weak or inaccurate noun out of a tight place."
That's actually not just three strikes, it's four, because in addition to contravening "positive form" and "active voice" and "nouns and verbs," it has a elative clause ("that can pull") removed from what it belongs with (the adjective), which violates another edict: "Keep related words together."
"Keep related words together" is further explained in these terms: "The subject of a sentence and the principal verb should not, as a rule, be separated by a phrase or clause that can be transferred to the beginning." That is a negative passive, containing an adjective, with the subject separated from the principal verb by a phrase ("as a rule") that could easily have been transferred to the beginning. Another quadruple violation.
