today's lesson is do not use downstairs or upstairs with prepositions, especially

prepositions like in, to , at or on. They don't need it. Let's look at the note

here. The words downstairs and upstairs already have the meaning of "to " or "on" a

lower floor, of course for downstairs or an upper floor for upstairs. So it

already has the meaning of the prepositions included in it. So if you

look up downstairs in the dictionary, it means like to or on a lower floor. If you

look up upstairs, it means two are on an upper floor. So you don't need these

prepositions to go with these words. Okay. Let's continue. Let's look at some

examples here. Of course with the X, this is where a student might make the

mistake and where it's wrong. So if the student said I went to upstairs to get a

book from my room. No. You should have just simply said here with the check. I

went upstairs to get a book from my room. So you didn't need to say " to" upstairs.

It's not needed here. Or again with the X, this is wrong. The bathroom is located at

downstairs. No. Again it doesn't take this

preposition. With the check, this would be right. You'd say the bathroom is located

downstairs. So no, no at, no in, no on. Okay. And the last one here with the X. The basement is

in the downstairs. Yeah. Definitely wrong. You should

say with the check here. The basement is downstairs. And that's another thing too

that students often make a mistake. You should never say something is in a floor

in a floor, it sounds like it's like underneath the wood or underneath the

tiles like you know, where the bugs may live. We usually say something is on a

floor. But in this case with downstairs and upstairs. You don't need any of those

prepositions. Anyway, I hope you got it. I hope it was clear. I hope it was informative. Thank you

for your time. Bye-bye.
