`Lexical self -dating' evidence for a common agro-pastoral origin of Sanskrit `gopati', `gospati' and Slavic `gospod', `gospodin' meaning lord/master/gentleman more than 8,000 years ago.

In the search for the origin and the original meaning of the Slovenian and Russian words gospod and gospodin meaning lord, master; and gost meaning guest; the answer is best found in the Vedic Sanskrit, particularly in the cattle herding terminology.

In this paper, the origin of words such as `gopati', `gospod' meaning lord, master and also `gost', meaning guest in the Indo-European languages will be examined from the point of reference to their probable agro-pastoral beginnings. The present Slovenian colloquial meaning of the word `gospod' is analogous to mister/gentleman, but Lord in a religious context. However, historically it was used in the sense of lord, master which indicated that the person had a dominion over others and that the person exercised this authority on the basis of property or religious rights. The Sanskrit `gopati' `gospati'and `goshpati' are analogous to the Slavic `gospod' or `gospodin'. In Apte's The Practical Sanskrit-English Dictionary (PSED) we can see that, Sanskrit `gopati' can mean an owner of cows, a leader, chief, king and in Vedic language a herdsman, protector, guardian, cowherd, a king; `goshpati' means a chief herdsman. This indicates that the origin was in an age, when the cattle were already domesticated and there had been an accumulation of wealth to a point, where some owners had other people looking after their livestock.
