-These three particles can all be used to indicate that you are doing (usually giving) something TO somebody. 에게, 한테 and 께 all have the same meaning, but ~한테 is usually used in conversation, ~에게 is usually written (although it is still said in conversation very often) and ~께 is used when the person you are giving something to requires respect (께 is the honorific form of 에게/한테).

 Also make sure that you realize that ‘for’ can have many meanings in English. Just because you say ‘for’ in English, doesn’t mean that it can be translated directly to ~를/을 위해. In Korean, ~를/을 위해 means **for the benefit of.** For example, in this sentence:
 
-I am waiting for the bus – the ‘bus’ is the object which you are waiting for, so, in Korean, you attach the particle ~을/를 to ‘bus’ but not ~을/를 위해:
+- I am waiting for the bus

-This isn’t incredibly important right now, but I thought I’d mention it. “위해” is actually a verb, and the base form of the verb is 위하다. When ~아/어/여 is added to 위하다, it changes to 위하여. This was first presented in [Lesson 5.](https://www.howtostudykorean.com/unit1/unit-1-lessons-1-8/unit-1-lesson-5/#vpast) 하다 officially changes to 하여 when adding ~아/어/여, but this is commonly shortened to 해. Therefore, it is possible to use “위하여” instead of “위해.” Technically, this is possible in any word that finishes in ~하다, but it seems to be much more common with 위하다 than any other verb or adjective.

 Just like with ~을/를 위해서, there is very little (if any) difference between ~에 대해 and ~에 대해서. For example, the sentences above could all be written as:
 
-나는 너에 대해서 생각했어 = I thought about you
-나는 나의 아버지에 대해서 말했어 = I spoke about my father
-나는 그것에 대해서 책을 쓸 거야 = I will write a book about it
-그 회계사는 정부에 대해서 나쁜 말을 했어요 = That accountant said bad things about the government
+- 나는 너에 대해서 생각했어 = <span class="md spoiler">I thought about you</span>

+- 그 회계사는 정부에 대해서 나쁜 말을 했어요 = <span class="md spoiler">That accountant said bad things about the government</span>
 
 One way that you cannot use ~에 대해 is in the following sentence:
 
-My favorite thing **about** you is your eyes.
+- My favorite thing **about** you is your eyes.
 
 I’d love to teach you that sentence in Korean, even though we haven’t covered the grammar, Ah, what the heck – I’ll show you – even though full understanding won’t come until [Lesson 28.](https://www.howtostudykorean.com/unit-2-lower-intermediate-korean-grammar/unit-2-lessons-26-33/lesson-28/)
 
-너에 있어서 내가 가장 좋아하는 것은 너의 눈이야.
+- 너에 있어서 내가 가장 좋아하는 것은 너의 눈이야.
 
 Too complicated for you right now, the grammar within that sentence will be discussed in [Lesson 28](https://www.howtostudykorean.com/unit-2-lower-intermediate-korean-grammar/unit-2-lessons-26-33/lesson-28/). Until then…
