hello grammarians alright today I want to start talking about conjunctions and conjunctions are this part of speech that has a very particular function in English and what it does conjunctions unite words phrases and clauses let me let me show you an example so if you want to talk about two things you could say it's like peanut butter and jelly or if we're going to paraphrase Eddie Izzard I might offer you the choice of cake or death and you could also describe something as being sad but true and these three are the most commonly used conjunctions because I would be remiss if I didn't mention the seminole conjunctions song that got me into the grammar game in the first place conjunction junction which I think was written by Jack Sheldon or performed by Jack Sheldon in like 1973 Schoolhouse Rock it's great look it up but what I'm going to talk about today is a mnemonic or a memory aid called fanboys you may have heard this before fanboys and this is how we remember the coordinating conjunctions and you don't need to worry about the name coordinating conjunctions we'll get to that later for now just remember fanboys for and nor but or yet and so fanboys we'll go through how each one of these are used over in the next screen follow me downstairs so we've got four and nor but or yet and so and each of them have a different basic function so let's let's review them for has this connotation you can use it the way you would use a word like since or because as in I do not eat buttons for they are not food you can see I'm combining these these two little sentences using the word for we're using this this for to explain my reasoning I do not eat buttons because they are not food and for is a simpler way to express that the conjunction and very elemental very conjunction combines one thing with another as in the kangaroo robbed the bank and torched the saloon rather a criminal kangaroo and you can see we're using an to combine these two ideas and we're saying this thing happened this thing also happened they happened together nor is similar to and but we use it to combine untrue things we use it to express negation so if I were going to talk about an angry tree spirit for example just to pull an example out of a hat I could say she won't leave her tree nor will she speak with humans we use but to express exceptions as in we used every building material but chewing gum right chewing gum is the exception to every building material we use or as a conjunction to choose between options as in would you rather have a pet bear or a pet giraffe we ask the hard questions in Khan Academy yet it's kind of like but except that we use it to express unexpected things so I'm just gonna write to the contrary as if I were Sherlock Holmes hollering at a confused Watson and to the contrary my good man Watson this is how we use yet I'll show you I want to leave yet I cannot so it sets up this kind of push and pull dynamic in a sentence is what yet does we set the expectation I want to leave and yet here's the unexpected what I'd say an ironic part yet I cannot I want to leave but unfortunately or but unexpectedly when you would say but unexpectedly just use yet and finally the last part of fanboys so shows consequences Dougal was allergic to sheep so he skipped the wool festival right so so we're trying to set up that as a consequence of the first clause Dougal being allergic to sheep the thing that follows is because of that he decided to skip the wool festival this is fanboys for and nor but or yet so these are all covered in the exercises you can learn anything David out
