The Korean language has different structures when it comes to using it in a conversation. For example, Koreans love to emphasize adjectives especially when describing something big or small. Additionally, most conversations in Korean involve the formal way of speaking the language so I should be more comfortable with that style of speaking.
I do not believe that a reference grammar will be useful to get better at Korean. Not a lot of languages are similar to Korean when it comes to speaking. However, learning a lot Chinese characters and knowing their meanings can help one figure out the definitions to many difficult vocabulary words in Korean.
