Use Korean children's books and beginner resources to learn the alphabet. Study and learn how to correctly pronounce each character. Say the sounds aloud to yourself so you can adjust and train your ear to the sounds you're supposed to be making.
Read more beginner material and start learning entire words. Try to memorize their meanings by using sticky notes around the house to help you remember everyday words like refrigerator, teapot and milk.
Study beginner resources that pertain to writing skills. Learn how to write Korean characters and then move onto entire words and sentences when you're ready.
Learn about and, subsequently, adjust your intonation when speaking Korean. If you want to correctly pronounce words in Korean, you must take proper intonation into account. Koreans use very little pitch when speaking and the language does not contain any accented syllables (as opposed to English that certainly does.)
Use basic Korean grammar books and other resources to learn about grammar. Study the differences between your mother tongue and Korean grammar. For example, you'll notice that Koreans place verbs at the end of sentences, and pronouns such as "I, you and he" are often omitted when speaking. Commit the grammar rules to memory and do a lot of beginner practice exercises and tests to hone your skills.
Use audio recordings to continually adjust and attune your pronunciation, intonation and grammar skills. Steadily add more vocabulary to your newly formed repertoire each day.
Hire a tutor or take part in language exchange sessions with a native speaker to further your knowledge and fine tune your speaking, reading and writing abilities.
Learn about Korean history and the culture. This is helpful because cultural norms and nuances are related to language acquisition and abilities.
