『Corrected Korean Spelling Lecture』 is based on the existing 『Revised Korean Spelling Lecture』 and supplements the contents of the Korean spelling, standard language regulations, and foreign language notation rules partially revised by the Ministry of Culture, Sports and Tourism notice on March 28, 2017.
Although it is not a comprehensive revision, the Korean Spelling Rules [Ministry of Culture, Sports and Tourism Notice No. 2017-12 (2017.
3. 28.)] was partially revised.
'The Korean spelling rules were revised to reflect the linguistic reality as some of the descriptions in the Korean spelling rules and the Standard Korean Dictionary did not match, causing confusion in the language life of the people.'
We have resolved spacing inconsistencies in the regulations and reorganized expressions and examples.
I am well aware that 『Revised Korean Spelling Lectures』 has been loved by readers.
I hope that readers will show their love and guidance for the 『Corrected Korean Spelling Lecture』, which was published as a result of the revision of 『Korean Spelling』.

Chapter 1 General Provisions

The spirit of the entire Korean spelling system, or what can be called the grand principles, is defined in three general articles.
A review of the contents of this provision reveals that it contains the following three elements:

(1) This means that standard language is the subject of spelling regulations.
(2) This means that words selected as standard language must be written faithfully according to their pronunciation.
(3) Even if it is a standard language and is written according to pronunciation, it must not be grammatically correct or distorted.

Based on the principle that these three elements should be well-matched and harmonious, a grand plan for future spelling regulations was established.
Among them,

(1) The first element will be covered in detail in the 『Standard Language Regulations』 of this book, so it will be omitted here, and only elements (2) and (3) will be examined.

(2) The second element is that the standard language is written with the pronunciation as we actually speak it, which is a very natural rule for Hangul, a phonetic alphabet.
However, if we look at examples of writing before the publication of the ‘Unification Plan’,
① An example of not being able to write down the actual pronunciation due to a previous writing habit
It is easy to write 'shoulder' as 'eotgae' (see Article 5)
It is easy to write 'Euteum' as 'Eutdeum' (see Article 5)
It is easy to write 'wisdom tooth' as ​​'love' (see Article 27).
② When writing Chinese characters, examples of pronunciations that are different from the actual pronunciation
‘Rest room’ is written as ‘lounge room’ (see Article 8)
Write 'anonymous' as 'nickname' (see Article 10)
'Birds of a feather flock together' is written as 'birds of a feather flock together'.
(See Article 13)
These examples are all based on historical notation or are incorrectly written examples. I believe that the pronunciation of examples based on historical notation would have been consistent with the letters of that notation at the time that the notation was adopted.
However, since pronunciation also changes with the times, I think that it is even more necessary in modern times, which insists on consistency in language and writing, to record the pronunciation used at present once it has changed.
(Refer to the standard language regulations in this book).

(3) The third element, that is, writing in a grammatically correct manner, is also very necessary.
If we write only the pronunciation of the standard language as it is actually used, it will be faithful to the second element above, but it will result in a significant decrease in reading efficiency.
chamberlain,
'Together' as 'value' (see Article 6)
'Smiling adult' to 'Wooderun, ? adult' (see Article 7)
'Same, same, same, same' to 'trap, trap, kata, gatni' (see Article 15)
'One by one' to 'Nannachi, Nannachi' (see Article 20)
If we write it down, the phenomenon of language is revealed as it is, but the rules of language, that is, grammar, cannot be established.
Notation that is not organized according to the rules of the language is quite inconvenient to read.
It is commonly thought that Hangul, a phonetic alphabet, should maintain a 1:1 relationship between letters and phonemes.
From that perspective, the content written in Hangul can be understood as a simple transcription of sound symbols.

However, understanding a concept through letters does not necessarily involve the mediation of phonetic symbols; rather, letters communicate directly with the concept without the mediation of phonetic symbols.
For example, there are few people who first think of the words 'together' and 'petals' when they see them.
Just as it is common to hear the phonetic symbol '죂가치죃나죂꼬니삐죃' with one's ears, it is also common to see 'ㄱㄱ'나'꽃잎' with one's eyes and immediately arrive at the concept that 'ㄱㄱ'나'꽃잎' has.
Therefore, when one concept is written with the same notation, reading efficiency is greatly improved.

Regardless of the language, there has never been a case where spelling was determined solely by phonetic rules.
Therefore, 『Korean Spelling』 establishes rules for sounds and forms (see Chapters 3 and 4), that is, grammar, so that words are written accordingly, even if they are slightly different from the actual pronunciation.

As mentioned above, the second element of “writing as it sounds” and the third element of “making it grammatically correct” may seem to be in conflict at first glance, but we cannot be bound to one side of the argument at any time, and they must be in harmony with each other.
It is necessary to pay attention to the use of the expression “as a rule” at the end of paragraph 1, which leaves room for exceptions.
The fact that 『Korean Spelling』 presents such a compromise can be said to be a consideration for the fact that letters are purely for the eyes.
