French missionary Dallet (1874) wrote in his book that there is significant difference between Chinese language and Korean language. The present author studied the relation between Persian language and Korean language. The present researcher tried to select several Persian words randomly, and he compared them with Korean words. The researcher used a Dictionary of Persian/French and French/Persian (Bau, 2008). And the title is ‘Are they similar or are they same origin, Persian language and Korean language? (0053-0061)’. < number Persian word (its meaning) Korean word (its meaning)> 0053-1 Sadd (obstacle) Seodbureun (not intelligent for doing the thing) 0053-2 Sadd (obstacle) Soseul daemun (a big and significant door) 0053-3 Sadd (obstacle) Seodtureun (not good at something) 0054 Esteqamat (tolerant to do something) Yeogie ggomareul gireuda (Here, I bring up the child) 0055 Gabela (a wise wife) Aga bella (Oh, you are going to have a baby!) 0056-1 Amud (perpendicular) Amudeun (Anybody is OK!) 0056-2 Amud (perpendicular) Amuteun (Anyway, it is good!) 0057 Xod dari kardan (abstain, endure) Keun sod dolligi hada (to turn a big casserole) 0058 Mizaba (hung gutter) Mit-zzog bwa (You, see the downward!) 0059-1 Da tamam-e (during) Na ddaemun-e (It is because of me!) 0059-2 Da tamam-e (during) Nae mom-e da ta (All of you, come to me and take on my body!) 0060 Bolug (age of maturity) Bulug (The bosom of the body is grown and curved) 0061-1 Aya (Is it true?)
