I have different theory- Yasir does not speak one language- as he is a traveller he uses several languages from different places! When you are going abroad and do not speak “mother language” in the country where you are, you speaking “broken language”, you are mixing words or try any words/translations- with the hope that person will understand you/ speak this language.,
Me Yasir ( Me/ I Am Jasir) – Me/ I am from English
Si, Jema ze harum (Yes, with good fragrance) (Si – Italian, Spanish, Yes, Jema- Swahili Good, ze- Polish with, ) Harum also can mean other things though...
Si! Haneka Ariki ( Yes, Dedicated to Master/ Lord/ Rich) Si – Italian, Spanish, Haneka- Hebrew Dedicated , Ariki from Maori Master
Yasu me halaka <greets you friendly> (Me legal & cheap) - Yasu – from Japanese- Cheap, me- Eye, or simple English me, halaka- from Hebrew legal, law.
Si, Ariki! (Yes, Master/ Lord!)- I would not be surprised if that means “Yes, Rich!” as Ariki is associated with Wealthy People.
His name means “to be rich”, derived from Arabic (yasira) meaning “to become easy”. I guess anyone who was on the markets experienced situation where someone is saying to you “sweetly” Master, Lady etc to sell products?
