Make sure that the answer is in detail, long, consistent with the context, and requires general knowledge of English. To be less repetitive, please vary your language for each question. Give a proper explanation to answer, and if necessary, provide the definition of various terms. And conclude your answer if it's long. If you have used other resources (e.g., Merriam Webster's.) to answer the question, include citations in your answer. You don't need to paraphrase the context of your resources, but make sure that your answer is consistent and complete.

Example Input: I heard an American radio personality, university graduate, was saying below. 'Me and Adam have discovered a lot of weird things since we came to Japan.' My question here is not about grammatical things like the difference between I and Me, but the naturalness of the expression itself. I have this question because the example above is actually not the only case. I have noticed the radio personality uses the same wording often, but the conversations between him and his radio program partner, Adam, always keep going just smoothly as if no weird wording were used. FYI, Adam is a Canadian, and he is also university graduate. How natural does that sound to you? Can we use that in some formal settings too?.
Example Output: Using 'me' (or indeed other object pronouns) like this generally considered to be grammatically incorrect, because a subject pronoun ('I') should be used as subject of the verb. In formal (and probably everyday middle-of-the-road) language, this misuse of object pronouns is to be avoided. You should use 'Adam and I', with 'I' after the 'and', because 'I and Adam' sounds awkward (and grandiose). But 'me' as a subject is relatively common in informal language. Certainly I remember using sentences like 'Me and Simon are going to the park' in the school playground, only to be rebuked by my teachers in the classroom. In the classroom we learn to say 'Simon and I are going to the park' instead, using a subject pronoun, because Simon and I are the subjects of the verb to go. If we have good teachers, we learn to check by removing the other person: 'Simon and I are going...' becomes 'I am going', which sounds ok, so we say it. This way, when the pronoun should correctly be an object pronoun, we get it right even when Simon is in the way: 'The dog attacked me' so 'The dog attacked Simon and me'. And we don't have to learn nasty words like accusative. If we didn't pay enough attention though, or had bad teachers, we'll think the rule is that you never say 'Simon and me' and always 'Simon and I'. So we start producing hyper-correct forms like 'The dog attacked Simon and I', where 'I' is a subject pronoun instead of the required object pronoun ('me'). Or 'Mr Smith give Simon and I the belt for bad grammar' (should be 'Simon and me'). And people who learnt this and in later life find some authority while avoiding dates with descriptivist grammarians might start hyper-correcting people who otherwise use their pronouns correctly (effectively? pragmatically?). This all gets scary pretty fast, and so we might instead fudge things by using 'myself' etc., which is also wrong, but less likely to draw ire: 'Myself and Simon are going drinking in the park', or 'the dog attacked Simon and myself'. Forms like these are common in colloquial speech in Glasgow, where I live, and not a million miles from the entirely correct 'I myself am going drinking', with 'myself' as an emphatic pronoun. But we can also take revenge on these ill-informed hyper-correct pedants and, to spite our expensive university educations, start dropping forms like 'Me and Adam have discovered a lot of weird things since we came to Japan' into our radio conversations. It's more fun than explaining to somebody that French has disjunctive pronouns and 1066 and all that so why can't English because 'Simon et moi allons au parc ce soir' is ok? It's more rootsy than opining that English speakers must have a pretty weak grip on grammatical case these days if Simon and Adam's getting in the way is enough to muck it up.... Maybe what we're really learning is that our American radio personality's gig researching weirdness in Japan is enough of an indicator of social prestige that he doesn't need the crutch of prescriptive grammar to get ahead, except of course when it came to writing the application to get the job in the first place. If they is a reasonably sophisticated user of language, perhaps with a penchant for swiping pragmatist linguists right, s/he can likely adapt xir pronouns to the situation, (un)consciously confident that good language is really all about communicative power... Or maybe instead we'll one day hear a radio programme regretfully imploring the grandchildren to invest in Grammarly after a later-life realisation that pronominal correction is a socio-political power play and hell, the history of English from the Anglo-Saxon swamp til now tells us that it's always more fun to wield power by proxy than receive hit like me, Adam and hyper-correct I did. Such digressions aside, I'm struggling slightly to think of a situation where saying 'Me and Adam' instead of 'Adam and I' without a change in word order or stress changes the meaning EXCEPT in terms of social signalling -- something I gather Japanese knows about. Maybe something like 'Sally saw Steven and I went home and had breakfast', versus 'Sally saw Steven and me went home and had breakfast'. But even here, putting a comma or pause in makes more of a difference: in 'Sally saw Steven and I, went home and had breakfast', Sally gets the food, whereas in 'Sally saw Steven, and me went home and had breakfast' the breakfast is likely me's comfort food. To summarise: in informal language it's quite frequent, potentially common, potentially natural, and doesn't really affect meaning. But please don't say 'Adam and me would be excellent choices for the post of Pronoun Safety Officer' in formal communication that matters.

Example Input: I'm trying to describe a situation in which a person prepares for an event, then realises the event won't happen, and so they undo their preparations, returning to a state of unpreparedness. Whenever I search for the opposite of 'prepare', I get words that describe a failure to prepare in the first place, or at best words that describe what happens to the preparations, not words that describe what happens to the person. Is there a word that captures what happens to the person as they return to a state of unpreparedness?.
Example Output: There is the phrase 'stand down' about which Lexico says stand down PHRASAL VERB 2 Relax or cause to relax after a state of readiness. If something doesn't happen soon, I reckon they'll stand us down. An ambulance crew was dispatched immediately, however they were stood down shortly after. They have got to accept that the war is over and stand down their army once and for all.

Example Input: This phrase is all over the internet. They will say that something is free as in 'free beer' and free as in 'free speech'. I have never really understood this. Are these the examples of two different types of 'free'?.
Example Output:
Wikipedia on Gratis versus Libre: Gratis versus libre is the distinction between two meanings of the English adjective 'free'; namely, 'for zero price' (gratis) and 'with few or no restrictions' (libre). The ambiguity of 'free' can cause issues where the distinction is important, as it often is in dealing with laws concerning the use of information, such as copyright and patents. And further: With the advent of the free software movement, license schemes were created to give developers more freedom in terms of code sharing, commonly called open source or free and open source software. As the English adjective free does not distinguish between 'for zero price' and 'liberty', the phrases 'free as in free beer' (gratis, freeware) and 'free as in free speech' (libre, free software) were adopted. [...] 'Free software is a matter of liberty, not price. To understand the concept, you should think of free as in free speech, not as in free beer.' Richard Stallman Emphasis added.
