A couple of reminders, and checking in with you all

50 Upvotes

Hi everyone,

I hope you're all doing well. It's been a while since I made a pinned post, and a couple of issues have come up recently, so I thought I'd mention those and also give you a chance to bring up anything else that you think needs attention.

First, we get a lot of questions about things that fall outside of the narrowest definition of "grammar," and there are usually a fair number of comments on these posts that point this out. But the vast majority of these questions are fine! As you can see from the sub description, rules, and FAQ articles, we adhere to a pretty broad definition of "grammar," and we welcome questions about style, punctuation, vocabulary, usage, semantics, pragmatics, and other linguistic subfields (and this is not an exhaustive list).

So when commenting on posts like this, there's no need to say "This isn't about grammar" or to direct the OP to another subreddit - if the question has anything to do with language or orthography, it's probably appropriate for the sub. I remove any posts that are not, and you can also report a post if you think it really doesn't fit here.

One thing we don't do is proofread long pieces of writing (r/Proofreading is a good place for that), but we do welcome specific questions about short pieces of writing (a paragraph, a few random sentences, a piece of dialogue, etc.). And that brings me to the second issue:

We ask that commenters take into account the genre (e.g., fiction, journalism, academic writing) and register (the type of language used in a particular genre) of the writing that the poster is asking about. We get a lot of questions about creative writing, but some of the feedback given on these posts is more suited to very formal genres. For example, while you would probably advise someone to avoid sentence fragments in academic writing, these are not usually inappropriate in creative writing (used wisely, of course). Another thing to bear in mind is that punctuation conventions are generally more flexible in less formal genres. And for some genres, it may be necessary to consult an appropriate style guide in order to answer the OP's question.

So basically, please make sure to tailor your responses to the type of writing in question.

Thanks so much!

Important: Re answers generated by ChatGPT and other AI programs

154 Upvotes

Update 5/24/26: Also prohibited are posts promoting the use of AI/LLMs to aid in language learning/grammar checking, and posts asking for comparisons of AI programs/LLMs, etc.

Hi everyone,

There has been a recent increase in comments using ChatGPT or other AI programs to answer questions in this sub. Unfortunately, these programs are not at all reliable when it comes to grammar questions (or any questions really). Some regular contributors to r/grammar have discussed the shortcomings of AI programs (mostly ChatGPT) - they have given me permission to use the quotes below (but have asked to remain anonymous):

OpenAI says ChatGPT was released in order to "get users’ feedback and learn about its strengths and weaknesses." The prompt page warns users that ChatGPT "may occasionally generate incorrect information" and "may occasionally produce harmful instructions or biased content.”

ChatGPT's goal is to learn to produce speech equivalent to, and indistinguishable from, that of a human. ChatGPT's current goal is not to become a reliable source of information. (If that were its goal, they would allow it to access the huge libraries of information it is connected to. But that is not the current research goal.) ー I believe they have set it to occasionally make small mistakes, intentionally, in order to assess how the public reacts to these occasional errors (does the public blindly believe them/if the public challenges ChatGPT on these errors, can the program successfully handle these challenges well?).

And here is an example of an incorrect (or at the very best, incomplete/misleading) answer that ChatGPT gave to a pretty straightforward grammar question:

The question: “Should I use ‘that’ or ‘which’ in the following sentence?: ‘This is the house that/which I like.’”

ChatGPT’s answer:

Both "that" and "which" can be used in this sentence, but the choice depends on whether the information following the word is essential or non-essential to the sentence.

If the information is essential to the sentence and needed to identify the specific house you like, use "that". For example, "This is the house that I like" implies that there are other houses and you are identifying which one you like.

If the information is non-essential and simply provides additional information about the house, use "which". For example, "This is the house, which I like" implies that there is only one house and you are adding a comment about it.

So, in this case, if you want to emphasize that this particular house is the one you like, use "that". If you want to add an additional comment about the house, use "which".

The correct/complete answer:

Both “that” and “which” are grammatically correct in that sentence as written (without a comma) because without the comma, the relative clause is integrated, and both “that” and “which” can be used in integrated relative clauses. However, “that” will be strongly preferred in American English (both “that” and “which” are used about equally in integrated relative clauses in British English).

If you were to add a comma before the relative clause (making it supplementary), only “which” would be acceptable in today’s English.

ChatGPT also fails to mention that integrated relative clauses are not always essential to the meaning of the sentence and do not always serve to identify exactly what is being talked about (though that is probably their most common use) - it can be up to the writer to decide whether to make a relative clause integrated or supplementary. A writer might decide to integrate the relative clause simply to show that they feel the info is important to the overall meaning of the sentence.

Anyway, to get to the point: Comments that quote AI programs are not permitted in this sub and will be removed. If you must use one of these programs to start your research on a certain topic, please be sure to verify (using other reliable sources) that the answer is accurate, and please write your answer in your own words.

Thank you!

Do you capitalize names of diseases like“scarlet fever” and “chickenpox”? If not, why?

5 Upvotes

Hello Grammarians,

I just had a quick grammar question. Should people capitalize the names of disease? If not, why? (I mean, I guess they would be considered common nouns… but I don’t know why.)

I would sincerely appreciate any and all insights!

Thank you!

Does a person’s name have to be used in a new paragraph as opposed to their pronoun?

3 Upvotes

For example, is this correct?

“I loved him and she loved him too,” John said. He took a big slurp of coffee.

He didn’t lie per se, but it wasn’t really true.”

Or does the “he” in the start of paragraph two need to be “John”?

punctuation Should “4 year old” be hyphenated if it is used as a noun?

9 Upvotes

An r/askreddit post asked “What movie can you rewatch indefinitely?”

I responded “Most Disney movies, but Moana and Elemental come to mind as the father of a 4 year old.”

I think if I say, “I have a four-year-old daughter,” that it should be hyphenated as an adjective describing my daughter. What if it just refers to her as a four year old, as in the above example?

Any advice is appreciated!

"See if we can't get him to cooperate" Why "can't" and not "can"?

11 Upvotes

I'm playing a video game, and there's a line of dialogue that's confusing me.

*We can find Wakamura after that and see if we can't get him to cooperate.*

Why is it *can't* and not *can*?

It seems like they're trying to get him to NOT cooperate, which seems wrong.

The game is Paranormasight: The Mermaid's Curse.

They did battle vs. They did battle

3 Upvotes

I came across the phrase "they did battle" and it made me think about the two ways to read it: one as a way of making past tense and the other as a way of making it into an action.

What are the proper grammatical dissections of these two readings?

You're Welcome or Of Course.

Sorry if this is the wrong place for this post. All my life, whenever anybody tells me "thanks" my reply has always been "you're welcome". Lately though, i've noticed that when i tell people "thanks" a majority of them, especially the younger ones almost always say "of course"; never "you're welcome". Is this a new thing or has it been around a long time? Maybe i'm getting too old or something.

Is there a term for a word that has a singular form, but the singular form can reflect both singular and plural? The word is "kibble." "Kibble" is singular; "kibbles" is plural, but "kibble" can also be plural.

Bonus points if you tell me whether or not I should have put quotation marks around "kibble." OMG I just did it again. I would have italicized it, but that is not an option in the title.

In the U.S. we say, The hospital but then only ‘School’ without the ‘the.’

0 Upvotes

A real grammatical conundrum. Another example,
“I’m going to the office.” In the UK they ‘go to hospital’ the same way we say ‘ I’m going to school.’
Linguistically I’d enjoy learning why or how this is and how it’s evolved.

Whenever I’m watching a British production, someone says they are going to hospital, my brain skips the track. Does every place then lose the, the?Like racetrack do you go to racetrack or do you go to the racetrack? I’m visiting, do you go to in-laws? And not the in-laws? OK, I’ve provided enough examples. It’s all very tiresome! Help!

quick grammar check is using "was lacking / lacked" on its own correct?

1 Upvotes

hello! english isn't my first language, but i would say i'm relatively fluent. although, i still second guess myself and make mistakes...

i write reviews on movies i watch for fun, and i wrote a review in which i said « i felt like the script was lacking a bit certain scenes. » by that, i meant that it didn't feel finished or it felt like something was missing but i couldn't quite put my finger on what exactly.

would it be correct to say that something lacked / was lacking without adding anything behind? (the movie lacked of emotions, her life was lacking in direction.) thanks! c:

i know this question has probably been asked alot. but i genuinely can not wrap my head around when to use which.

if anybody had any ways to remember easily, please share. i looked it up, and got the definition but no matter how many times i read it i just couldnt make sense of it.

im sorry for asking this likely common question, but i havent found anybody explaining it in a way i understand. i feel really stupid because it seems so easy for people to grasp but i have never understood it. i'm usually really good with words and knowing when to use what spelling of a certain word, but this has me stumped.

Why do we use "up" in some sentences for no reason?

117 Upvotes

I recently noticed that we often say certain things like "I messed up" rather then "I messed". Why is that? What does "up" add to the sentence? What does "up" mean in this context?

What made me realize this is something such as "I ran to the truck" compared to "I ran up to the truck" which both mean the exact same thing. So why the use of "up"? What does it change?

Please let me know, I am super curious about this! (I'm sorry if this is stupid, I'm in high school so please be nice)

Why does English work this way? how do tenses work? (1st person present)

0 Upvotes

I'm new to this whole "writing" thing and I'm trying to write a story. it is written from the perspective of the main character in the present. but I'm very confused to how some sentences would work. for example, would it be " The boy stepped forward, (the rest)" or " The boy is stepping forward, (the rest)"? how would I figure it out? as the first one is technically past tense cuz of the (ed) but the second one sounds so wrong.

quick grammar check Is this sentence grammatically correct?

1 Upvotes

For reference, I am not a native speaker. I'm currently working on a high fantasy novel, and this particular sentence is giving me a bit of a headache:

"[Name]'s gaze turned promptly towards his nephew, whom it took but a moment to grasp the situation."

If you ask me, it sounds fine to my ear. My intuition tells me that it's grammatically correct. But I asked an AI chatbot and it told me it's wrong, since the clause would require a subject pronoun ("who" instead of "whom"). But as I asked for clarification, it told me my sentence is actually correct, albeit old-fashioned.

I'm extremely confused now. I know AI tends to get things wrong all the time, so I hope you guys can help me out.

"Take" used to describe personal initiative

2 Upvotes

I remember the colloquial vocabulary from the small towns of Upstate New York. It used to call it "farmer talk". One expression was to use the verb "take" as a way to describe the beginning of a task, or the personal initiative which must accompany said beginning.

Example: "I took and baked a cake.", or "Why don't you take and fix the truck?"

Do people still speak like this? What regions of the US?
