At first was the name! We have already said that this yellow plaything is called a "komboloi". Now listen carefully to the meaning of that word. It is a compound word. The main part is "kombo" and the suffix is "oi". Kombo is a knot, but according to an ancient Greek interpretation "kombo" means a knock, a sound heard when two hard objects of the same material clash. The suffix "oi" means a line of similar objects. So a line of knots or beads strung on a thread that move and knock against one another give us the picture of a "komboloi"
