There are three kinds of particle: subject particle, topic particle, and object particle. Subject particle have two forms, 이 and 가. 이 used for a noun that have a consonant ending, like 연필, 가방, 책, and many more. 가 used for vowel ending, like 내, 우유, 남자, and many more. Topic particle also have two forms,은 and 는. 은 used for consonant endings and 는 used for vowel endings. Object particles (again) have two forms, 을 an 를. 을 used for consonant and 를 used for vowel... May this help! If you want to get some more answer, kindly message me okay :)

Particles are things you add to the end of a word to give it a new meaning. For example, in English, you can add 's' to 'book' to make it plural. (one) book ---> (two or more) books. In Korean, that would be 책 (book) ---> 책들 (books). You added the particle 들. Or you could add the particle 이---> 책이 to make it the subject of a sentence.
