If you're wondering how to make a sentence with:
I AM / YOU ARE / HE SHE IT IS / WE ARE / THEY ARE here you are!
In Korean there's only one way to express all of these and that's with simple 이다 (이야/이에요-예요 /입니다).
Don't get confused - all of the four expressions I've stated, mean the same thing ! As if you probably already know, Korean has 4 honorific levels.
이다 - the verb is in infinitive form - by using this you can make the sentence sound formal ,but a little bit unnatural if used in a conversation
입니다 - high politeness level
이에요 - 예요 = formal (to people older than you )
if the word ends with consonant e.g. 학생 (ends with ㅇ ) we use 이에요
if the word ends with vowel e.g. 모자 (ends just with 자) we use 예요
이야 - informal (use to close friends or those younger than you)
if the word ends with consonant e.g. 학생 (ends with ㅇ ) we use 이야
if the word ends with vowel e.g. 모자 (ends just with 자) we use 야
USE:
제 이름은 (name) 입니다/ 내 이름은 (name) 이에요 / 나는 (name) 이야
= My name is (name).
저는 (age) 살입니다 / 나는 (age) 살이에요 / 나는 (age) 살이야
= I am (age) years old.
저는 (country name)사람입니다 / 나는 (country name)사람이에요 / 나는 (country name) 사람이야
= I am (nationality). - e.g. I am Chinese.
저는 학생입니다 / 나는 학생이에요 / 나는 학생이야
= I am a student.
그것은 내 모자입니다 / 그것은 내 모자예요 / 그것은 내 모자야
= That is my hat.
