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 more complex number system and the domestic pig from the more advanced Indo-Europeans to 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, they should show agreements in basic vocabulary, with more agreements if they are closely related, fewer if they are less closely related.
