Let's look at more examples!

있어요 [i-sseo-yo]

And in our examples, let's use the following words:

물 [mul] = water / 친구 [chin-gu] = friend / 시간 [si-gan] = time

You simply add at the end of the noun that you are referring to.

1. 물 . [mul i-sseo-yo] = There is water. / Water exists. / I have water. / They have water.

2. 물 ? [mul i-sseo-yo?] = Is there water? / Do you have water? / Do they have water?

3. 친구 . [chin-gu i-sseo-yo] = I have friends. / I have a friend. / There are friends.

4. 친구 ? [chin-gu i-sseo-yo?] = Do you have friends? / Do they have friends?

5. 시간 . [si-gan i-sseo-yo] = There is time. / I have time. / They have time.

6. 시간 ? [si-gan i-sseo-yo?] = Is there time? / Do you have time? / Do they have time?

And just by replacing [i-sseo-yo] with [eops-eo-yo] you get sentences in the opposite meanings.

없어요 [eop-sseo-yo]

1. 시간 . [si-gan eop-sseo-yo] = There is no time. / I don't have time. / We don't have time.

2. 친구 없어요. [chin-gu eop-sseo-yo] = I don't have friends.
