N + (으)로
(으)로 is a noun particle that means by, with or direction.
Depending on how we use it, this particle can mean many different things:
1. (으)로 can mean ‘to’ somewhere when used with a location noun and a moving verb like 가다.
2. (으)로 can mean ‘by’ or ‘with’ when used with a noun and a verb that uses that noun.
3. (으)로 can mean ‘by’ or ‘from’ when used with a noun and a verb that explains the cause and effect.
Basically, (으)로 is a particle that ties some method, or reason between the noun and the sentence.
