One of the things that foreigners have a hard time learning Korean is 'number'.
There are two numbers in Korean : 'Unique numbers' and 'Arabic numbers'.
Unique numbers are pure Korean, and Arabic numbers are influenced by Chinese to pronounce them.
The problem varies depending on the situation, so many foreigners find it difficult to learn.
Especially, the number that represents time is one of the hardest things for foreigners.
■ Regular time 4:10 [네시 십분]
■ Public time 17:20 [십칠시 이십분]
In Korean, it is pronounced as a unique number when it refers to 'hour', and Arabic when it refers to 'minute'.
However, in public time, it is very confusing because time numbers above 10 are pronounced Arabic.
