Korean has been influenced by Chinese and incorporates many English loanwords known as Konglish. After World War 2 and the Korean War, more foreign cultures entered South Korea. Konglish words entered the Korean language through Japanese occupation and by South Koreans adapting English words to Korean phonetic rules. This causes English words to be pronounced differently in Korean with added vowels or changed consonant sounds. Konglish also impacts sentence structure and vocabulary meaning compared to English.
