How to Use Noun(으)로

When (으)로 is used after nouns, it has two basic meanings.

Frist, (으)로 expresses a direction (toward a place). It means ‘to’ or 'toward' in English. When the preceding noun ends in a vowel or ㄹ , 로 is used, and when the noun ends in a consonant, 으로 is used.

Example:

앞으로 쭉 가세요. 우체국이 있어요 Please go straight forward. There’s a post office.

What is the difference between –(으)로 가다 and -에 가다?

-(으)로 가다 expresses going toward a particular direction, with the focus being on the direction. While on the other hand, -에 가다 focuses on the destination, and thus only the destination is expressed because no sense of direction is conveyed.

Focus on direction:

에릭 씨가 집으로 가요. (correct) Eric goes to his home.

오른쪽으로 가세요. (correct) Go to the right.

Focus on destination:

에릭 씨가 집으에 가요. (correct)Eric goes to his home.

오른쪽에 가세요. (wrong)

Second, (으)로 is also used when expressing means of transport, tools, materials used to make

 something. This meaning corresponds to ‘by’ or ‘with/using’ and ‘from’ in English

Example:

부산에 기차로 갈 거 예요 I’ll go to Busan by train.

가위로 종이를 잘라요 I cut the paper with scissors.

밀가루로 빵을 만들어요 I make bread from flour.
