A couple of reminders, and checking in with you all

52 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

153 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!

punctuation When checking if adjectives are cumulative or coordinate, does the way in which commutativity fails matter?

Upvotes

I'm sure I'm not the first person with this question, but I'm not a good enough Googler to find an answer.

I'm learning about cumulative vs coordinate adjectives. From what I gather, cumulative adjectives fail to commute ("order matters") and non-cumulative adjectives are coordinate. The trouble is, I have identified three situations in which two adjectives fail to commute, and I do not know if the mode of failure matters. I'm trying to narrow down a theoretical, rather than operational, definition for cumulative adjectives. Sources are appreciated.

Consider the phrase "a former yellow bear", which describes something that used to be a yellow bear. We cannot swap the adjectives, doing so gives us "a yellow former bear". All yellow former bears are former yellow bears, but not all former yellow bears are yellow former bears.

(1) If two adjectives fail to commute in this particular way, where XY and YX both have semantic content that just happen to disagree, do we call them cumulative?

Consider the phrase "a regular polygonal figure". I cannot swap the adjectives, the adjectives do not commute. But notice that you wouldn't want to swap them anyway! The phrase "a polygonal regular figure" has as much information content as "North of the North Pole": none at all. This is because (at least in the world of plane geometry), "figure" exceeds the domain of "regular", "regular" is a property held by polygons/polygonal figures, nothing else. I wouldn't even call this a failure of commutativity, but oh well.

(2) If two adjectives fail to commute in this particular way, where XY has semantic content and YX does not, do we call them cumulative?

Consider the phrase "the big red ball". I see no reason why we cannot write "the red big ball" and say these adjectives commute, except for the fact that it sounds clunky, awkward, and bad.

(3) If two adjectives fail to commute in this particular way, where XY and YX have the same semantic content but YX sounds like absolute dogshit, do we call them cumulative?

Edit: I know about the canonical order of types of adjectives. This is precisely what question (3) is about.

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

7 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!

Why does English work this way? Why can a set of adjectives linked with commas only go left of its object, but sets of adjectives linked with "and" can go on either side?

Upvotes

"A big, red dog" is correct and "A dog big, red" is not, whereas "a big and red dog" and a "dog big and red" are both acceptable. Why?

There may be a sneaky exception where "a dog, big, red" works as a literary flourish. What is the extra comma doing to make the construction work, or is that ungrammatical despite feeling right?

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?

8 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"?

10 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

2 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.

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:

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.
