아 에 이 오 우(가) 악 엔 임 온 웃 (이)
A good way to remember it is that the final consonant takes the place of ㅇ when pronouncing them
ex. 한국이 would sound like 한구기
What's the difference between having 이 at the end of a noun and 가 at the end?
책 ends with a consonant, ㄱ, so it gets 이. 사과 ends with a vowel, ㅏ, so it gets 가.
I was wondering why. Thank you!
Same
long as in length and width? or long as in the story is long?
The story. 가로 or 세로 or 길이 might have actual measurements associated with them.
when do we use 그 and 그???
It says the is 그 but 그 is never an option °ㅡ°
Even if the site/app says it "그" doesn't mean "the". 그 can mean "the" but it can also mean "that".
"그" is used for something closer to the person you're speaking to and farther away relative to you.
It said the answer was to put 을 at the end
The answer that the site accepts for this question doesn't contain "을" at all.
Also, 을/를 is the object marker and Korean grammar always places the object (if there is one) in the middle.
