@JTT,
JTT: Since you brought up Bryan Gardener as a scapegoad for the evils of prescriptivism, I submitted your alleged myths of prescriptivist linguistics to a test: I looked them up in Gardner's
Modern American Usage (2003), checked if I can find the prescription there, and, if I found it, checked what the reasoning was.
JTT wrote:'that' for restrictive clauses vs 'which' for non-restrictive
Garner (2003) notes that there are two schools on the matter: one that cares about the distinction on the matter, and that doesn't. He makes a snarky remark expressing his partisanship for the former, and proceeds to offer guidelines for those who wish to obey the distinction. Not much of a prescription here.
JTT wrote:split infinitive
Never been categorically prohibited in actual prescriptivist literature.
JTT wrote:No 'can' for permission
Isn't much of a prescription. Garner (2003), under "can", has this to say: "Although only an insufferable precisian would insist on observing the distinction [between
may and
can] in informal speech (especially in questions such as "can I wait until August?") it's often advisable to distinguish these words. That's not a prescription, that's a soft guideline.
JTT wrote:No 'was' for the subjunctive mood
Doesn't seem to be prohibited: I looked up "was" and "subjunctive" in Gardner, and found no prohibition.
JTT wrote:No sentence ending prepositions
Not prohibited according to Gardner. In his article on prepositions, he speaks unkindly about grammarians who use Latin grammar as a straightjacket for American usage.
Definitely no prescription here.
JTT wrote:No conjunctions to start sentences
Same deal as for ending sentences with prepositions.
The other alleged myths aren't specific enough to look up in a prescriptivist book. But what I could look up seems good enough to make my point: The lion's share of your myths are
not peddled by Gardner, the epitome of prescriptivist evilness of your choice. What he does peddle are loose guidelines that seem utterly sensible to me.
So far, there isn't a single item on your list that a) is advocated by Garner and b) you have proven to be a myth.
