I’ve been teaching in Korea for awhile and these would always come up in the classroom. Most students didn’t know the English for many of the symbols (especially exclamation point) and I realized I didn’t know the Korean for them. Knowing these will be useful especially for those teaching in Korea.
Some great books to get your started are Korean Made Simple: A beginner's guide to learning the Korean language and Become a Hangeul Master: Learn to Read and Write Korean Characters
