The present researcher has read Persian words from the Alphabet-written dictionary (Bau, 2008), and he found the similar aspect with Korean language.So he supposed that the two languages came from the same origin. This time, the present researcher tried to find out similar words between Persian language and Korean language. And the researchers compared several similar words between the two languages through pronunciation. The investigating order and its number is randomly chosen. From the 10 words investigated here, there are two words which the present researcher cannot translate correctly; ‘dast zadan’ and ‘dhu’l qa’deh’. So the researcher tried them two times. And the meaning of ‘zaye’at’ in Persian language and that in Korean language is opposite.
