Consonant and Vowel Mapping

The input system maps Romanized consonants and vowels to their respective Hangul characters. For example:

• k becomes ᄀ (as a final)
• t becomes ᄐ
• a becomes ᅡ
• o becomes ᅩ

Syllable Construction

The input system follows the traditional structure of Korean syllables, which is made up of:

• Initial consonant (or nothing if it’s a vowel-initial syllable)
• Vowel
• Final consonant (optional, if there is one)

For instance, the syllable "ga" is constructed from:

• Initial: ᄀ (g)
• Vowel: ᅡ (a)

Special Letter Rules

Several consonants and their combinations (like double consonants) are mapped according to specific rules:

• g becomes ᄀ (as an initial)
• kk (double consonant) becomes ᄁ
• b becomes ᄇ
• bb becomes ᄈ

Syllable Final Consonants

The final consonants (받침) in Korean are also handled by the input system, so when typing Romanized syllables that end with a consonant, they are mapped to the corresponding Hangul final consonant:

• k at the end of a syllable becomes ᆨ
• t becomes ᆮ
• l becomes ᆯ

Diphthongs and Vowel Combinations

When you type certain vowel combinations (like diphthongs), the input system converts them to their correct Hangul representation:

• wa becomes 와
• wo becomes 워
• ya becomes 야
• ye becomes 예

Typing Romanized Korean

To write in Korean using this input method, you type out the Romanized text. For example:

• Type "annyeong" (which means "hello" in Korean), and it will automatically convert to "안녕."
• For more complex words like "seonggyeong" (to represent a name), typing it will convert it to "성경."

Automatic Combination of Jamo

When you type individual jamo (the basic components of Hangul—initial consonants, vowels, and final consonants), they will be automatically combined into the corresponding syllable block. For example:

• Typing g followed by a results in 가.
• Typing k, a, and t together results in 칻.
