In fact, most of the spelling mistakes we make are ones we wouldn't even know we made if we said them out loud.
But in the process of transcribing this into text, your knowledge of spelling is revealed.
The problem is that these days, we have a lot more to read and write about. With the advent of social media and the widespread adoption of smartphones, we communicate with people through messengers and post on social media dozens of times a day.
And that writing is seen by other people.
It also means that there are more instances where your spelling skills are revealed to others.

When referring to "earrings," is "earrings" or "earring hooks" correct? Both are correct.
Words that are both recognized as standard languages ​​are called plural standard languages.
Originally, only 'earrings' was the standard word.
In the 17th century, it was called 'Gwiyeotgolhoe', and in the 19th century, it was called 'Gwiegori', which is how it became the current 'Gwigori'.
If you look at the etymology, it seems closer to ‘ring’ than ‘hook’, so it was written as ‘earring’.
However, there is a Korean proverb that says, “If you hang it on your nose, it is a nose ring, and if you hang it on your ear, it is an earring.”
Also, as people used the word 'earrings' a lot, they came to be recognized as standard language.
But 'earrings' is the wrong word.

What do you say to lengthen the hem of your pants? The correct answer is "Please lengthen it."
'Neulrida' and 'Neulida' have similar meanings and pronunciations, so they can be confusing, but they are used differently, so they should be used differently.
'Neulida' is a word mainly used to indicate length.
Since the hem of a trouser is made longer, we use the word ‘늘이다’.
Also, when you want to make your hair hang down, as in 'grow your hair long', you use '늘이다'.
On the other hand, '늘리다' is mainly used when increasing the area or volume, as in 'increase the size of a store.'
When the number or amount increases or the weight increases, such as ‘increase subscribers’ or ‘gain weight’, ‘increase’ is also used.

The pencil that was clearly on my desk just moments ago disappeared, I saw a dog walking on two legs like a human, rain falling under a clear sky—is that a "strange event" or a "strange thing"? When you want to express wonder at something rare, it's appropriate to say "strange."
'희안하다' is a non-standard form of '희한하다'.
'Heehanhada' is a Chinese character that combines 'hee (稀),' meaning rare, and 'han (罕),' meaning rare.
Since the word rare appears twice, it must mean that it is really rare.

'Together' can be written either attached or separated.
The reason is that 'together' can be used as a particle or adverb.
When 'together' is attached to a noun (noun, pronoun, numeral) and used as a particle meaning "like the typical characteristic of the preceding word," it is attached to the preceding word.
So, 'like a picture' must be written together.
When 'together' is used as an adverb with 'wa/gwa' to mean 'together', it is written with a space in front of the word.
In 'with me', 'together' is used with 'wa/gwa' to modify the verb 'to leave', so it is correct to write it with a space in front of the word.

The best way to become familiar with correct Korean spelling is to read a lot of text written correctly.
First of all, I recommend reading a lot of books.
Reading books not only allows you to gain specialized information in various fields, but also broadens your horizons by indirectly experiencing things you haven't experienced before.
The book's advantages don't end there.
Another advantage is that it is written in a way that is correct in spelling.
The book contains refined language that has undergone meticulous proofreading by the author and editor.
So, if you read a lot of books, you will naturally be exposed to a lot of correct notation forms.
As you get used to it, you will find yourself knowing which spellings are correct and which are incorrect without even realizing it.
So it is important to read a lot of books.
Also, whenever you write something, whether it's an email, message, or report, it's a good idea to be conscious of the spelling of the words you use and check them repeatedly.
