Such words as those for "hundred", "pig", and "king" have something in common: they represent "cultural vocabulary" as opposed to "basic vocabulary". They are likely to have been acquired along with a novel number system and the domestic pig from Indo-Europeans in the south. Similarly, the Indo-Europeans themselves had acquired such words and cultural items from peoples to their south or west, including possibly their words for "ox", *gʷou- (compare English cow) and "grain", *bʰars- (compare English barley). In contrast, basic vocabulary – words such as "me", "hand", "water", and "be" – is much less readily borrowed between languages. If Indo-European and Uralic are genetically related, there should be agreements regarding basic vocabulary, with more agreements if they are closely related, fewer if they are less closely related.
