You know how we make words plural in English by adding an "s", or an "es", or sometimes changing the "y" to an "ies", or changing the word into something totally different, or doing nothing to it at all?
dog=>dogs
fox=>foxes
pony=>ponies
mouse=>mice
deer=>deer
Well, in Korean if want to make a word plural there is only one way to do it and that is by adding 들 (-deul) to the end.
And much of the time you don't even have to do that! If the people you're talking to already know there are more than one of the object you don't need to make it plural. Or, in some contexts it actually doesn't matter if there is more than one of the object. Like for example if I said "You should take off your rings when you play basketball" It doesn't matter if you are wearing one ring or more than one. It's the same message.
Only when it is important and when it is not already obvious is when you need add 들 (-deul) to make a word plural in Korean.
If you are specifying exactly how many of something there is by putting a number in front of it. Then it is definately obvious that the noun is plural (or singular) so the deul is not required. HOWEVER, Korean has these things called "Counters" and if you want to talk about how many of something there is you'll need to know how to use them. And that's the next lesson.
