We know that there are at least 2500 hanjas that are used in modern Korean.
I want to know synonymous hanjas like 불 and 무 (무료 and 불합격). These two hanjas are kind of negation prefixes.
There might be synonymous hanjas that mean big or the best or the most or any other word ( I am just guessing here).
So, what are some similar in meaning hanjas used in Korean?
