I cant understand this in English either due to my dyslexia though it is making it hard to understand when to use it in Korean even more so!
I know if it ends in a vowel you use '가' and if a consonant its '이', though I am can not understand when you use it and when you dont. I am working through Lingodeer lessons I cant see the 'reason' why you sometimes use it and sometimes dont. It says on my app 'indicate what the subject of an action (verb) is. Though that doesnt help me 'understand', can anyone put it in another way for me please?
