In Korean the structure of sentence differ to English sentences, for example the phrase "Chal Chinaessooyo" literally means "Well have you been getting on?" which is the opposite from English. In general the structure of the Korean sentences is broken down as "subject - object - verb".
Although the grammar is not that difficult, a reference grammar can definitely be helpful especially for us beginners. I am going to learn some basic grammars by reading grammar books online and ask my Korean friends for help. I will document every new grammar I learn in my notebook so that I can review them easily.
Since the Korean grammar structure is quite different from English, I am going to do a comparison for each new grammar to help me memorize and understand. For example, in Korean unlike English, the subject of the sentences is optional like "I", then the "in order section" is next, which is then followed by "the place you are going".
Also there are a few words that you may add to the end of verb stems at the end of sentences, these include "yo" which makes sentences polite, and "ro" which means "in order to".
