The concept of a convenient way for the ancients has a great importance. The meaning of ka-le is preserved in many languages around the world. The Crimean-tatar kele in all its variants is related to the tatar kil (to come), slang khilyat (to go), oblomkam (words parts) in Russian: dokole (to the something (place, month, time)) or dokel. This is also the meaning of the English goal and not very pleasant to modern man the word kal (feces), which were strewn with the way of migration of animals and which for ancient hunters was a guiding star in search of prey. So my ancestors the Greeks kept the familiar greeting in their language. Kali Mero now sounds like good day, where Kali is for good, and mero is for day (from our word mera (measure) is a part of the time, the same root of the word smert (death)). But the original meaning of this greeting-wish had the meaning of good journey. And the answer, as the password, was not less kind Kalu Sirtys.
