hello grammarians so we had said previously that prepositions Express relationships between two ideas right and we can do that either in time or in space or in other ways but today I want to talk about prepositions in space [Music] because this is again one of the things that prepositions do is they can set up relationships between objects and their locations right so I could say the triangle is over the square right or on top of the square I could say the circle is inside the square right and these are all over inside what I would like to do is review some of the major ones and and talk about what their uses are so when we use the word at in a sentence and here I'm talking about is something we should note is that some of these prepositions can be used in multiple ways right so so at has a space connotation but it also can have a time connotation but I don't want you to really worry about that right now I think it makes the most sense to just think of their their uses as as separate and just think of them separately so when we talk about at and means a point that's talking about a point so we could say something like we stood at the entrance to a cave but it can also have this connotation of direction as in the creature launched itself at Ameena the word by when we're talking about space means near as in the house by the old mill is totally haunted and all these sentences are like really spooky the preposition from has this connotation of coming from somewhere else to here as in we came from Mars in denotes enclosed area so you could say something like there's a bunny in the box off denotes you know away from she hopped off the rock on which you know didn't usually notes being on a surface as opposed to in which is in an enclosed area right like I said so we could say there's a goblin on the front steps right the Goblin is on the steps the bunny is in the box do you see the difference out is another direction word and you know away from something right and off and on and in and out I mean the opposite of each other so away from out means away from an enclosed area and off means away from a surface so if you can imagine you know there's someone who's on the rock and then they hop off the rock there's a goblin on the front steps and maybe the Goblin leaves the front steps he's off the front steps there's a buddy in the box if the buddy leaves the box it will go out of the box and there's plenty of other prepositions but let's let's talk about to which when you're talking about to in the physical sense it has this connotation of direction so you could say I'm going to Mozambique these are some of but certainly not all of the spatial prepositions of English now we're lucky because prepositions are a closed group in English enclosed group we don't we don't add many of them to the language the way that we add nouns and adverbs and verbs and adjectives there are a lot of them and you have to memorize all of them and their various obnoxious nuances but there isn't a limitless number of prepositions there's you know maybe a hundred plus and of those you know maybe fifty are quite useful and of those maybe twenty to twenty-five are super useful and it's the super useful most common ones that are in the exercises so give those a go you can learn anything Dave it out
