Input: Consider 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'?.

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.


Input: Consider Input: I often read the expression 'would of' used instead of 'would have'. Each time I read it I get annoyed so I googled it and found out -as I expected- that it is an incorrect way to say 'would have'. Now, there are a lot of brilliant slang words/expressions, so my question is, why do people use this one? It's so annoying to read, stupid and clearly wrong, it is pointless, why did they come up with this expression? Edit: I don't think my question is a duplicate as I didn't ask how can somebody use it (since I know it's incorrect and I know that I can use it with commas giving it a different meaning) but I asked why and how people came up with this expression.

Output: Correction: what annoys you is people writing 'would of' when they are saying /wdv/, which is the standard pronunciation of the contraction would've. The vowel of the preposition 'of' is almost always reduced in actual speech, yielding /v/. Thus 'would've' and 'would of' are homophones. So no surprise that some people spell it that way, even though it makes no grammatical sense. Would've can be even further reduced to /wd/, which some people spell woulda as a kind of phonetic eye dialect to represent actual speech or set an informal tone. The same goes for the modals, shoulda, coulda, musta. Spelling as it sounds can yield amusing results: Along the way the details of his past are sordid out and he realizes that what he once thought about his parents isn't the truth at all. Amazon.com Review. A speaker of British English, of course, would never write sorted in this manner, but with an American flapped t, it's a perfect fit.


Input: Consider Input: How does one correctly apply 'in which', 'of which', 'at which', 'to which', etc.? I'm confused with which one to apply when constructing sentences around these.


Output: The trick to knowing how to use; of which, at which, in which, to which, from which is to analyse the prepositional phrases, phrasal verbs, verbs and prepositions: He /spoke of/ war and peace and many other topics that day. The topic /of which he spoke/ was complex. The verb here that means to speak about a topic is /to speak/ of a topic/: to mention The party /at which/ he spoke/ was noisy. Phrase: A party is held /at a place/. It is implied. The situation /in which/ we found ourselves was dire. Phrase: /to find oneself /in a situation. The bonds /from which/ we broke free were tight. phrase: to /break free/ from bonds. The town /to which/we were driving was 50 ks away. phrase: to /drive/ to a place. Summary (and not a complete answer but a general one): The preposition depends on the verb that takes a preposition, a phrasal verb that includes a preposition, or it depends on the prepositional phrase used. Also, there are many other prepositions that can be paired with which: under, during, about, over, etc.
