query: What is the reason for the differences in the Korean language between North and South Korea?
answer: The differences stem from the prolonged separation of North and South Korea, influencing dialectal divergence through government policies and isolation.  This led to differing vocabulary choices (e.g., loanwords from English in the South vs. Russian in the North), orthographic variations, and pronunciation differences.
