This exchange between Donuel and me took place on the Roe v. Wade thread, where it was out of place, so I've edited it extremely heavily in order to remove abrasiveness and moved it over here. It all started when he misused the word "supersedes," compounded by his rather perverse misspelling of it:

ME: "Supercedes" [sic]??

HE: “Sic” is an adverb that means “thus” in Latin, but writers and editors can also use it to highlight grammar errors in quoted text. Learn the proper way to use “sic” and useful alternatives.

It would be better to use "recte" and write the word correctly spelled if you want to correct spelling...

ME: [sic] means that I have quoted your rendering of the word in question exactly, even though I know it to be incorrect. For five hundred years the word has been "supersede," and you won't find many authorities that don't regard "supercede" as either perverse or ignorant.

...And it was the wrong word to use in any case.

HE: Please continue to use [sic] incorrectly, "recte" is more correct for a single word.
A spelling error, horrific, hoisted by ones own petard, devine.

ME: The phrase is from Hamlet, and the correct version is hoist with his own petard. I use it quite a lot, only ever that way, the right way, just as I use [sic].

I've never used, let alone heard of, "recte," and the examples of its use that I looked up all look cumbersome and somewhat obscurantist. I think that [sic] is perfectly good for both single words and for phrases and I can find no objection to that anywhere. Feel free to demur!
