English usage lore is full of myths and hobgoblins. Some have the status of zombie rules, heeded by millions despite being bogus and illegitimate since forever (split infinitives, preposition-stranding). Other myths attach to particular words and make people unsure how to use them ‘properly’ (decimate, hopefully), leading in some cases to what linguists call ‘nervous cluelessness’ about language use.
These myths spread and survive for various reasons. On one side is the appeal of superiority. On the other is fear of embarrassment: We play it safe rather than risk ridicule and ‘correction’. We are (often to our detriment) a rule-loving species, uncomfortable with uncertainty and variation unless we resolve not to be. We defer to authority but are poor judges of what constitutes good varieties of it.*
So if a self-appointed expert on English asserts a rule, some will lap it up no matter its validity. The unedifying results are laid bare in reference works like the Merriam-Webster Dictionary of English Usage (MWDEU), which, with rigour and wit, summarises centuries of confusion and argument over whether A or B is correct when often both are or each is appropriate in a different variety of English.
Huge effort is wasted on such trivialities. So, as a quick exercise in myth-busting (and amusing myself), I posted an A to Z of English usage myths on Twitter last week. Reactions were mostly positive, but some items inevitably proved contentious, as we’ll see.
You can click through on this initial tweet for the full A–Z plus supplements on Twitter, or you can read the lightly edited version below, followed by extra notes and quotes now that the 140-character limit doesn’t apply.
