Polite Style (ํด์์ฒด) ~์์/์ด์; also a lengthy explanation about vowel contractions
Polite style is usually the first level of speech taught to foreigners, probably because it's generally hard to offend someone accidentally by speaking politely.
The dictionary form of a verb or adjective consists of the stem + ๋ค. Polite style is formed by dropping the ๋ค ending and adding ~์์ or ~์ด์ to the verb or adjective stem:
์๋ค to be small; drop ๋ค and add ~์์:
์ ํ ํค๊ฐ ์์์.
Jonghyun is short. (lit. Jonghyun's height is small.)
๋จน๋ค to eat; drop ๋ค and add ~์ด์:
ํ๋ฏผ์ด ๋จน์ด์.
Taemin is eating.
How do you know whether to use ~์์ or ~์ด์? You look at the vowel in the verb/adjective stem. Generally speaking, if the vowel in the stem is ์ or ์ค, use ~์์. If the vowel in the stem is anything else, use ~์ด์. There are some exceptions, the most common being that ํ๋ค becomes ํด์, despite the ์ vowel in the stem.
~์์ ending:
์ข๋ค to be narrow > ์ค in stem > ์ข์์
์งง๋ค to be short > ์ in stem > ์งง์์
~์ด์ ending:
๋๋ค to be spacious, wide > ์ด in stem > ๋์ด์
์ฃฝ๋ค to die > ์ฐ in stem > ์ฃฝ์ด์
~ํด์ ending:
์น์ ํ๋ค to be kind > ํ๋ค stem > ์น์ ํด์
Although this seems a little arbitrary, it's far from it.
Korean vowels are organized into "light" and "dark" vowels. Light vowels only couple with other light vowels, and dark vowels with other dark vowels. My Korean professor used this handy diagram to help remember which vowels are light and which are dark (excuse my very rudimentary art skills):
Notice that the ใ
and ใ
sides of the box are illuminated by the lamp light. These are the "bright" vowels. The ใ
and ใ
are the "dark" vowels.
You may have noticed that the examples above all had consonants at the end of the stem. When the stem ends in a vowel, it becomes a little more complicated because there is opportunity for vowel contraction.
In verb or adjective stems that end in ์ or ์ด, the vowels contract with the result being that ~์ alone is added to the stem:
๊ฐ๋ค to go > ์ contracts with ~์์ > ๊ฐ์
๊ฑด๋๋ค to cross > ์ด contracts with ~์ด์ > ๊ฑด๋์
In verb or adjective stems that end in ์ค or ์ฐ, these combine predictably with the polite ending to form the diphthongs ์ and ์:
์ค๋ค to come > ์ค combines with ์ to form diphthong ์ > ์์
์ถค์ถ๋ค to dance > ์ฐ combines with ์ด to form diphthong ์ > ์ถค์ถฐ์
But what about the rest of the vowels? How do they contract?
Much like the bright/dark distinction, there is also a strong/weak distinction that dictates how vowels interact. My wonderful Korean professor explained this as a sort of Mortal Kombat tournament where the various final vowels fight against ์ด.
์ is the strongest vowel. It easily overpowers ์ด, and knocks it out of the picture completely. (The boring, linguistic reason for this is that ์ is already a diphthong, and so it can't combine to form another).
๋ณด๋ด๋ค to spend time > ์ overpowers ์ด and is unchanged > ๋ณด๋ด์
์ผ is the weakest vowel. It doesn't even wait to encounter its opponent before lying down in defeat. (Get it? Because ์ผ looks like a person lying down?) When you encounter a stem that ends in ์ผ, ignore it completely and refer to the vowel in the syllable before it to decide whether it takes ~์์ or ~์ด์. If there is no syllable, use ~์ด์.
๋ฐ์๋ค to be busy > ์ผ is deleted, ์ is used > ๋ฐ๋น ์
์์๋ค to be pretty > ์ผ is deleted, ์ด is used > ์๋ป์
์ฐ๋ค to use, to write > ์ผ is deleted, ์ด is used > ์จ์
์ด is a lover rather than a fighter, so when it encounters ์ด it combines to form ์ฌ. I never really understood why it becomes ์ฌ (wouldn't ์ be the more logical combination of ์ด and ์ด?), but I just imagine that the ์ด is sort of a slut, and so it jumps up onto the ์ด to do the horizontal tango.
There is a notable exception to the ์ด rule: honorific ~(์ผ)์ combines to make the more logical ~(์ผ)์ธ์ polite ending. (If you really want to be confused, the past tense honorific is (์ผ)์
จ์ด์, which follows the regular rule! What the hell, Korean?!)
์น๋ค to hit > ์ด combines with ์ด > ์ณ์
๊ฐ๋ค to go + honorific (์ผ)์ > ์ด combines with ์ด > ๊ฐ์ธ์
past tense: ๊ฐ์
จ์ด์
You'll maybe notice I left out ์. I assume that ์ follows the same rule as ์ , as it is also already a diphthong, but I can't think of anything right now except for the phrase "๊ธ์์" ("it's hard to say") that uses it, and I'm not even sure that the base of that is ๊ธ์๋ค. Google search seems to think so, but Google search is often wrong. Feel free to correct me or offer suggestions.
