past tense - "Why couldn't" vs. "why couldn't you have"


Reading Harry Potter 2, I came across the following, and I wonder if the use of couldn't have is the equivalent of couldn't in this context?



"I have got a question, Oliver," said George, who had woken with a start. "Why couldn't you have told us all this yesterday when we were all awake?"



If we change it to the following, how does it change the meaning of it?



"I have got a question, Oliver," said George, who had woken with a start. "Why couldn't you tell us all this yesterday when we were all awake?"



And what is the difference between the following?



If you couldn't do it, you should have told us yesterday.


If you couldn't have done it, you should have told us yesterday.

etymology - Origin of "s--t eating grin"

What is the origin of the phrase shit eating grin ? How did it come to mean showing smugness or self-satisfaction of an individual's actions? Answer From the Urban Dictionary: ...these uses are documented in the Oxford English Dictionary no earlier than 1957 There have been similar expressions used quite far back: In Book XXI of his History of Rome, Livy describes a Carthaginian sect of coprophages, the risus faecivorus, or shit-eating grin, being commonly displayed by its adherents. Although, its origin is undetermined, they may have been incidents which caused the invention of this phrase. Below is an excerpt: "1944 Jrnl. Nerv. & Mental Dis. XCIX. 959 Among demented patients in advanced stages of their illness,..it is not rare to see some of them grasp their own feces, chew them and eat them often with great pleasure and satisfaction (coprophagia).

etymology - Since when has "a hot minute" meant a long time?

The term a hot minute can be found all over blogs and in casual speech, meaning essentially, "a long time." The term is mostly slang, but seems to have become popular enough to appear on sites as reputable as PBS.org. Delia pretends to be mad about it for a hot minute but gets over it pretty quickly because the love of her life is finally home. I can't find it defined in reputable dictionaries, but The New York Times confirms the meaning in this article about slang uses of the word "hot." Hottie is still bandied about on campus by not-quite-with-it seniors, and a hot minute is defined as “a long time.” There is life left in the cleaned-up meaning of hot mess, which has come to mean “disheveled” or “incompetent,” as in “I was a hot mess this morning before I hit the shower.” The term reminds me of "A New York Minute," which means the exact opposite, "a very short time." So what is the origin of the term "a hot minute," and how lo...

etymology - Why "silver-tongued" for someone who is convincing?

I understand that "silver-tongued" or "silver-tongued devil" means to be a good orator, or: able to speak in a way that makes other people do or believe what you want them to do or believe Merriam Webster My question is: why silver ? This question on quora goes into detail about where & when the phrase appears to originate from. But why would silver be chosen as the adjective to describe someone's tongue? I'm making the assumption that it means the valuable metal silver and not simply the color, but would gold not have been more apt, as it is worth more? Or why not jewel encrusted tongue? It just seems rather arbitrary to choose a valuable metal, but not the most valuable, to describe someone with a tongue that is valuable. I was wondering if there is any evidence of a deeper or more substantial meaning as to the original choice. Answer It does not refer to the value but to the " sound " produced by silver objects: Of voices, words, etc., fr...

usage - "there doesn't seem" vs. "there don't seem"

As an example, consider the two sentences: There don't seem to be any doctors here. and There doesn't seem to be any doctors here. To my ear, the first sounds great, and the second is painfully awkward. So which is correct, grammatically? I've found lots of disagreement on this around the Web, with various sources citing different ways of treating the word "any" (as singular, always, or as either depending on to what it refers). No consensus, however, could I locate. Answer The relevant article in ‘The Cambridge Guide to English Usage’ says: Existential there couples with either singular or plural verbs ( there is / there are , according to the following noun phrase) . . . This formal agreement is strictly maintained in academic writing. But in narrative and everyday writing, there is and especially there’s is found even with plural nouns. The same consideration applies to There don’t and There doesn’t . What it means for your examples is that it all depends ...

etymology - Origin of "queer as a clockwork orange"

While reading a recent Ken Follet novel, I came across the following, spoken in a gay bar set in early sixties London: "I am queer as a clockwork orange, a three-pound note, a purple unicorn, or a football bat." Previous to this, I had thought that "clockwork orange" was a phrase made up by Anthony Burgess to describe something that is impossible as a title for his 1962 novel. Checking further, I found that Burgess had actually borrowed this phrase from something he supposedly overheard in a pub. From the 1986 introduction " A Clockwork Orange Re-sucked " I don’t think I have to remind readers what the title means. Clockwork oranges don’t exist, except in the speech of old Londoners . The image is a bizarre one, always used for a bizarre thing. “He’s as queer as a clockwork orange” meant he was queer to the limit of queerness. It did not primarily denote homosexuality, though a queer, before restrictive legislation came in, was the term used for a member o...

First floor vs ground floor, usage origin

Ground floor – First floor: In British English, the floor of a building which is level with the ground is called the ground floor. The floor above it is called the first floor, the floor above that is the second floor, and so on. In American English, the floor which is level with the ground is called the first floor, the floor above it is the second floor, and so on. (Collins COBUILD English Usage) Though there are exceptions to the above-mentioned usage,( and exceptions are not the issue here) in public buildings in the U.S., for instance, it’s also possible to call the street-level floor the ground floor, like in Britain, but how come that in the UK and Europe the ground level floor and the first floor are respectively referred to as the first floor and the second floor in the U.S. (and so on for higher floors) . Was it a custom imported into the U.S. from a different culture? Related: "Ground floor" vs. "first floor" .

meaning - What is meant by "don't piss on my boots and tell me it's raining"?

I have heard a couple of times recently the phrase "don't piss on my boots and tell me it's raining", usually in the context of a heated argument so I've hesitated to ask speaker what exactly he meant by it. Can anyone here help? Answer It suggests that the person you're upset with is harming you, making an unbelievably brazen claim that they are not, and that you have seen through their meagre attempt at deception. There are a few variant forms. There's pee versus piss for varying the level of crudity, and even spit to avoid the subject of urine entirely. The thing being urinated (or spat) on can be a boot, shoe, leg, back, face, etc. Some examples: Gal, you can't spit in my face and call it rain. [spoken to one who is trying to deceive.] Boy, you can't piss on me and tell me it's raining. (from Honey, hush! An Anthology of African-American Women's Humor by Daryl Cumber Dance, 1998, p88) Senator : The war's over. Our side won the ...
