"That man has an older brother and an older sister."
Translation:그 남자는 형하고 누나가 있어.
This is one way:
그 남자는 남동생 둘, 형 하나, 그리고 누나 둘 있어요.
There are a lot of ways to say "That man has two younger brothers, one older brother, and two older sisters." This is because there are many ways to form a noun phrase like "two older sisters" and many ways to form a list in Korean.
Just make sure you form one of the appropriate noun phrases for each set of siblings:
- Noun+Number+Counter (사람 한 명)
- Number+Noun (한 사람)
- Number+Counter+의+Noun (한 명의 사람)
- Noun+Number (사람 하나)
Here we use the fourth pattern and repeat it in the sentence because parallelism helps the reader/listener. We will also mirror the English list with its Korean counterpart using the connecting word 그리고. We also drop the subject marker since the context makes the subject complement of the existential verb apparent.
