Well there are few ways to express passive voice or "피동" in Korean. The ways of expressing passive voice are called 피동법. 피동법 as I mentioned is several: 1) 접미피동법. Way of forming passive voice by suffixes. Of course not every word takes these suffixes though. These suffixes do have some rules on when they are used but that's too detailed. If you still want to know them though, I could write them out :D These are used to form passive voice are: -이-; -히-; -리-; -기- as suffixes. Examples: 쓰다 -> 쓰이다; 먹다 -> 먹히다; 듣다 -> 들리다; 안다 -> 안기다. 2) -(아/어)지다 피동법. Way of forming passive voice using -(아/어)지다. As you may already know this grammar point is used on adjectives to express change in form/state, however when used with transitive verbs it forms a passive voice. This way just like 접미피동법 cannot be used for every verb. Examples: 만들다 -> 만들어지다. However: 읽다 -> 읽어지다 is wrong. In cases like these you can use the 접미피동법+(아/어지다) 피동법 읽다 -> 읽히다 -> 읽혀지다. 3) Another way to make passive are suffixes: -되다; -받다; -당하다. These suffixes are applied on nouns. 사용-하다 -> 사용-되다 사랑-하다 -> 사랑-받다 이용-하다 -> 이용-당하다 From my knowledge -받다 is uncommon and only added on several nouns and -당하다 carries a negative meaning. For example: 이용되다 1) to be utilized (for good) 2) to be exploited (to one's advantage) 이용당하다 1) to be exploited (to one's advantage) However already negative roots still share the same meaning. 해고되다 <-> 해고당하다 Nearly forgot your second question! "Apple was eaten (by me)" would probably be "사과가 나에게 먹혔다" Leaving off further morphology/syntax to you :D
