Is there a term or concept that describes instances where an author/speaker intentionally or knowingly uses wrong spelling/pronunciation/grammar because it better conveys the intended meaning, and is therefore used by the author/speaker in place of the correct spelling/pronunciation/grammar, exclusive of instances of the author simply quoting someone else? (e.g. a character who uses incorrect grammar wouldn't count, since that was (presumably) intended by the author).
Here are some examples I have encountered in the wild (I'm sure there are better ones):
If you’re completely new to SQL you might start with this codeacademy tutorial.
This misspelling of codecademy as codeacademy is arguably slightly more readable, especially to those who haven't heard of it before.
This should have a possessive apostrophe, but the name doesn't use one, probably because it becomes less catchy, less easy to write etc.
I've seen this occur where it makes communication more practical, for example, during a short interaction (especially when at some nexus of travellers all with different accents/pronunciations), if someone mispronounces a word, it is sometimes easier to use their mispronunciation than to risk them not knowing what is meant when the correct pronunciation is used. In this case, the first instance is an unintentional mispronunciation (so it's not relevant to this question), but the second mispronunciation is intentional.
I came across this quote from Oscar Wilde's letters to the St. James's Gazette:
Now, as regards grammar, I hold that, in prose at any rate, correctness should always be subordinate to artistic effect and musical cadence; and any peculiarities of syntax that may occur in Dorian Gray are deliberately intended, and are introduced to show the value of the artistic theory in question.
So Wilde appears to say he would have no issues deliberately making grammatical inaccuracies.
Is there a term to describe such instances where intentionally incorrect spelling/pronunciation/grammar are preferred by the author to the correct ones?
