I'm of the opinion that so long as it is understandable it does not matter. English was once written as it sounded and there was no spelling consistancy. Those who were literate had little issue with it.

Edit: Okay my rant is more related to spelling than grammar but still interesting.

In German there's the saying "macht Sinn", which is wrong since it's just a direct translation of "makes sense". Correct would be "ergibt Sinn", in English "results in sense", but I don't care, "macht Sinn" rolls off the tongue easier.

abbreviations. it doesn't save any meaningful time. it only prompts questions for clarification because people don't define the abbreviation prior to using it throughout their post. plus since everything is being abbreviated out of laziness, the same abbreviations get used for multiple things which just adds additional confusions.

It's not a grammar mistake per se, but I feel like sharing it and it is close enough so here we go.

As a non-native English speaker: How can you have mop~~b~~ and vacuum the floor but not broom the room?! I know it doesn't exist, but I don't care. If we have to phrase it as a grammar mistake: I use verbalisations where they are uncommon.

I do not like the way that unspaced em dashes look. More generally I don't think that having distinct em and en dashes is actually useful anyway, you can absolutely just use an en dash in either case with absolutely no loss of clarity or readability, but I do need to use em dashes for some work writing so I have a key on my keyboard for it and use it semi-regularly. Whenever I use an em dash outside of a professional context I space it. So, "he's coming next Monday — the 6th, that is — some time in the morning," as opposed to the more broadly-recommended, "he's coming next Monday—the 6th, that is—some time in the morning."

I have absolutely no reason for this other than subjective aesthetic preferences, but it has coincidentally become somewhat useful recently. LLMs notoriously use em dashes far more than humans but consistently use them unspaced, so it's a sort of mild defence against anything I write looking LLM-generated

Anything that is used colloquially but technically isn't correct because some loser didn't like it 200 years ago. To boldly keep on splitting infinitives is a rejection of language prescriptivism!

I dont care about capitalizations, apostrophes, or if you shorthand words like tho as long as i can understand what youre saying from the context

Sometimes a sentence ending with a proposition just sounds better.

Being excessively prescriptive or nitpicky about the prohibition on ending sentences on a preposition is the sort of nonsense up with which I will not put.

I'm really sick of people treating AAVE and other dialects like grammar mistakes, is what. Grammar Nazis indeed, protecting the purity of the English language.

Im over spellcheck on phones. I'll look the other way when something is typed all wacky from a phone.

Singular they. I've had this opinion since long before I even knew about non-binary people. Using "he or she" to refer to a person without specifying gender is clunky as hell.

'irregardless' and improper 'begs the question' are both fine.

What incorrect grammar are you completely in defence of?

Ending a sentence on a preposition :3c

Ending a sentence with a proposition is just fine. Picky people whom I've only seen parodies of on the Internet go "oh you ended your sentence with a preposition I have no idea what you mean by 'He went in' maybe you could explain what he went into? A jello mold? A ditch? What did go into?"

You asked if he went into the store and I said he went in, you know what I meant because of CONTEXT CLUES.

I've never met anyone who's ever been this picky but I'm ready to bite them if I ever find one.

If punctuation isn't on your keyboard then it can't be that important. All dashes are the same.

I don't even appreciate that Markdown turns double-dash into one long dash. The distinction in print is a twee relic of uptight style guides, and the minute gradations do not exist in handwritten text. If you intend it as a pause-please, put spaces around it, or it looks dumb. Like that.
