Indo-European languages across most of Eurasia. Personal names The use of two-word compound words for personal names, typically but not always ascribing some noble or heroic feat to their bearer, is so common in Indo-European languages that it is certainly an inherited feature. These names often belonged in early dialects to the class of compound words that in the Sanskrit tradition are called bahuvrihi. As in Vedic bahuvrihi (literally "much-rice", meaning "one who has much rice"), those compounds are formed as active structures indicating possession and do not require a verbal root. From the Proto-Indo-European personal name *Ḱléwos-wésu (lit. "good-fame", meaning "possessing good fame") derive the Liburnian Vescleves, the Greek Eukleḗs (Εὐκλεής), the Old Persian Huçavah, the Avestan Haosravah-, and the Sanskrit Suśráva. A second type of compound consists of a noun followed by a verbal root or stem, describing an individual performing an action. Compounds more similar to synthetics are found in the Sanskrit Trasá-dasyus ("one who causes enemies to tremble"), the Greek Archelaus (Ἀρχέλαος, "one who rules people"), and the Old Persian Xšayāršan ("one who rules men"). Many Indo-European personal names are associated with the horse (*h₁éḱwos) in particular, which expressed both the wealth and nobility of their bearer, including the Avestan Hwaspa ("owning good horses"), the Greek Hippónikos ("winning by his horses"), or the Gaulish Epomeduos ("master of horses"). Since domestic animals also served to sacrifice, there were often used as exocentric structures in compound names (the bearers are not 'horses' themselves but 'users of horses' in some way), in contrast to endocentric personal names rather associated with wild animals like the wolf, for instance in the German Adolf ("a noble wolf") or the Serbian Dobrovuk ("a good wolf"). Economy Proto-Indo-Europeans possessed a Neolithic mixed economy based on livestock and subsidiary agriculture, with a wide range of economic regimes and various degrees of mobility that could be expected across the large Pontic-Caspian steppe. Tribes were typically more influenced by farming in the western Dnieper-Donets region, where cereal cultivation was practised, while the eastern Don-Volga steppes were inhabited by semi-nomadic and pastoral populations mostly relying on herding. Proto-Indo-European distinguished between unmovable and movable wealth (*péḱu, the "livestock"). As for the rest of society, economy was founded on reciprocity. A gift always entailed a counter-gift, and each party was bound to the other in a mutual relationship cemented by trust. Trade The early Khvalynsk culture, located in the Volga-Ural
