OF Is More Than “의”: The Hidden Meanings Behind One of English’s Most Useful Words

OF Is More Than “의”: The Hidden Meanings Behind One of English’s Most Useful Words

Korean learners often memorize of = “의”.

That works sometimes.

But not always.

In real English, of can express possession,
connection, material, quantity, identity, cause, characteristics,
and even the essential nature of something.

So “of” is not just a translation.
It is a relationship word.

1. OF for Possession

This is the meaning most learners know first.

The roof of the house
집의 지붕

The name of the company
회사의 이름

But English often prefers ‘s for people.

John’s car
존의 차

sounds more natural than:

The car of John

Understand the relationship.

“Of” is a tiny word.
But it carries a surprisingly big job.
