I'm trying to understand is there any difference between how you use: 放棄 and 丟棄 or are they interchangeable? Ans: 放棄 像是 give up。 EX: I give up playing the guitar. 我放棄彈吉他。 She doesn't give up easily. 她做任何事都不輕易放棄。 丟棄 像是 throw away。 EX: Don't throw away those boxes. 不要把那些箱子扔掉。 Can you throw away the trash? 你可以將垃圾丟掉嗎？ 希望能幫助到你：）

放棄一個動作 丟棄一個東西

放棄+a event e.g.放棄資格 放棄means you have this quality originally,but you get rid of it now. 丟棄+a thing (a pen,a bottle, garbage) 丟棄Means you don't want a thing,so you thow up it.
