Should we adopt a standarized way to indicate that we're writing a sentence that is incorrect?
Yo soy bien.(I've used it in in this answer)
- *Yo soy bien.
- ×Yo soy bien.
The first example makes clear the part of the sentence that is incorrect. The second example would make sense to linguists, but others would probably go looking for a footnote for the asterisk at the bottom of the question. The third example could be interpreted as a bullet point, or just referring to the first word and not the whole sentence. The first seems like the best option to me.
In general though, I'd say people should use whatever they're comfortable using. This seems too specific of an issue to solidify a standard and go around editing posts and policing people's formatting.
Well, I vote for the second one, personally.
It's true it's mostly used by linguists, but it's kind of the most spread way to signal not an "incorrect" sentence, but an ungrammatical sentence.
In any case, let's wait for more opinions on the matter and see what the tendency is.
It probably depends on context.
*I intentionally spelled asterisk incorrectly so I'd have an excuse to demonstrate my meaning.
