In Korean, there are many particles. However, most of them are fairly straightforward (maybe a bit less once you start getting to advanced grammar). I'm assuming you're talking about the first basic three particles that are absolutely essential (though often omitted in casual conversation and chat messages) to creating basic, grammatically correct Korean sentences. These are 은/는, 이/가, and 을/를. Do you know 은 vs 는, 이 vs 가 , and 을 vs 를? I don't mean each particle pair compared to one another (not 은/는 vs 이/가 vs 을/를) but when to use one versus the other within a pair. Each pair itself has a different meaning compared to the other pairs. Both words within each pair have the exact same meaning but are used at different times 은 = 는 이 = 가 을 = 를 Each pairing has identical meaning. However, when you use one word versus the other within the pair depends on the letter that comes before it. This is the same concept as "a" and "an" in English. a = an They both mean the same thing (one; an indefinite article). However, when you use one versus the other within that pair depends on the sound that comes after it. a comes before a consonant SOUND (a ball, a horse) an comes before a vowel SOUND (an egg, an hour)

Thank you I understand a bit better now :)

It denotes the direct object of a sentence. Ex. I eat rice. -> RICE I drink water. -> WATER I bought a bag. -> BAG The object is in all caps. 나는 밥을 먹어요. -> 밥 나는 물을 마셔요. -> 물 나는 가방을 샀어요. -> 가방 In all of those examples, the direct object just so happened to end in a consonant so I used 을. 나는 사과를 깎았어요. -> 사과 (I peeled the APPLE) 이/가 vs 은/는 is usually where people get stumped.

When figuring out which one to use within the pair, look at the LETTER that comes immediately BEFORE it. NOT the SOUND that comes immediately AFTER it. *These rules apply when 은 & 는 are being used as particles and not as part of a grammar point, where it may vary slightly. But as far as particles go, this is it. No exceptions! 은 is used when the LETTER immediately before it is a CONSONANT 는 is used when the LETTER immediately before it is a VOWEL 이 is used when the LETTER immediately before it is a CONSONANT 가 is used when the LETTER immediately before it is a VOWEL 을 is used when the LETTER immediately before it is a CONSONANT 를 is used when the LETTER immediately before it is a VOWEL Do you understand when to use each particle within each pair correctly? Not worrying about WHEN to use that TYPE of particle or the meaning/overall usage. Just 은 vs 는, 이 vs 가, and 을 vs 를. Not worrying about 은/는 vs 이/가 vs 을/를. I think part of what makes it hard for people to learn a foreign language (heck, even their native language in a more advanced form) is that people don't understand how their language and language in general works. You cetainly don't need to be a linguist or language major to learn some important basics. These include the parts of a sentence, parts of speech, etc. (Subject, object, topic, pronoun, independent/dependent clause, coordinating/etc conjuction, contraction, compound noun, punctuation, etc are all vocabulary and things to be aware of) Thus, learning your own language better and how language works can actually help you learn other languages better.
