Korean lessons: Lesson 5

Nominal predicates : “–이에요”

Sample Dialogues

By ‘nominal predicate’, we mean a predicate of a sentence that describes the subject by identifying it with another noun: “I am a student.”  For verbs and adjectives, we learned that there are base forms and stems.  We thus get base forms, “가다” for “to go”, and “싸다” for “to be cheap”, etc.  Now, we are facing a new problem.  If there is no such thing as the English verb “to be”, how are we going to say such sentences as “I am a student”?  Many languages lack the verb like “to be,” which can be used both in nominal predicates and adjectival predicates. (“I am a student” and “I am tall”.)  In order to relate two nouns (i.e., the subject and the nominal complement), such languages use so-called ‘copula’.  In Korean, that copula is “-이다”.  “-이다” is of course the base form, which still has to be conjugated to be used in actual sentences.  Hence, “학생이다” (“to be a student”); “구름이다” (“to be clouds”).

True stories of the present-tense suffix -요 and -세요

In Lesson 4, -요 and -세요 were introduced.  It was, however, not exactly everything that we should know about them.

1) Mid-polite suffix -아/어요

Verbs and adjectives that we practiced with for -요 suffix in  Lesson 4 have something in common: they all have the stem ending in vowel ? without any patch’im followed (‘가다’, ‘자다’, ‘싸다’, etc.)  Those whose stems end otherwise, should take either -아요 or -어요.  The last vowel of the stem decides which of the two to take.  Once again, the vowel harmony principle (‘yang with yang; yin with yin’) applies:

If the stem has a yang vowel at the last syllable, use -아요;
If the stem has a yin or neutral vowel at the last syllable,  use -어요.
(For yang/yin/neutral vowels, see Lesson 2.)
작다
to be small
: 작 + -아요 작아요
“It’s small.” or “He/She is small.”?
오다
to come
: 오 + -아요 (오아요) → 와요
“Come!” or “I come” or “He/She comes.”
괜찮다[괜찬타]
to be alright
: 괜찮 + -아요 괜찮아요 [괜차나요]
“It’s OK.”
주다
to give
: 주 + -어요 (주어요) → 줘요
“Give (me, etc.)!” or “I give.”
먹다
to eat
: 먹 + -어요 먹어요
“Eat!” or “I eat.” or “He/She eats.”
읽다 [익다]
to read
: 읽 + -어요 읽어요 [일거요]
“Read!” or “I read.” or “He/She reads.”

In fact, 가다 → 가요 is a contraction  [가 + -아요 → (가아요) → 가요], so are the others in Lesson 4.

(NB) -하다 verbs and adjectives are rather peculiar.  For them, -여요 is assumed instead of -아요.  This may sound quite overwhelming, but -하다 words are in fact easier.  All the -하다 stems with no exception appear as -해요.

일하다
to work
일해요
공부하다
to study
공부해요
착하다
to be nice (person)
 착해요

2) High-polite suffix -(으)세요

Although not so complicated as -아/어요, this suffix also has its own rules:

If the stem ends without a patch’im, use -세요;
If the stem ends with a patch’im, use -으세요.
가다 : 가 + 세요 가세요
웃다  to laugh : 웃 + 으세요 웃으세요
안녕하다 : 안녕하 + 세요 안녕하세요
괜찮다 : 괜찮 + 으세요 괜찮으세요 [괜차느세요]

“오영균이에요”

Finally, we arrive the detail structure of “안녕하세요. XXX(name)이에요.”  Since personal names are the same as nouns, we use the nominal-predicate copula, -이다.  In order to make it into a real sentence, we need to add either -아요 or -어요 in place of the base-form making -다 after -이-.  For 이 is a neutral vowel, -어요 is added.  -이어요 had gone through a certain phonological change in modern Seoul speakers’ speech, and ended in -이에요.

오영균 이다 →오영균 이 + -어요 → 오영균이에요 “I am Oh Young Kyun.”

Similarly,

학생: 학생이에요 “I am / You are a student” or “He/She is a student”

기차: 기차이에요 “It’s a train.”

There are two forms to spell this -이에요: -예요 and -이에요.  As far as we are concerned, just -이에요 suffice.

    Hey, thanks for the website !
    Where can I find the answers of the practices ? As I’m not sure of mine 🙁

  • learnkorean com

    We did not make answers to these practices. We will look into them and make answers sometime in the future.

    • ZeX

      Thank you for the good work and the answer though !

    I lived in Seoul for 5 years due to work and so as you can imagine, I had to learn the Korean language in a very short space of time. Just offering my advice to anyone else looking to learn this language and that is to follow the Rocket ‘Learn Korean’ program at:

    http://solution2solve.com/learnkorean

    It worked very well for me as I was completely fluent in the language in well under a year from following it and I didn’t have to pay massive teacher fees like my work originally advised to me. An absolute life saver :);’;
