Morphological The most common arguments in favour of a relationship between Indo-European and Uralic are based on seemingly common elements of
morphology, such as the pronominal roots (
*m- for first person;
*t- for second person), case markings (accusative
*-m; ablative
*-ta), interrogative/relative pronouns (
*kʷ- "who?, which?";
*y- "who, which" to signal relative clauses). Other, less obvious correspondences are suggested, such as the Indo-European plural marker
*-es (or
*-s in the accusative plural ) and its Uralic counterpart
*-t. This same word-final
assibilation of
*-t to
*-s may also be present in Indo-European second-person singular
*-s in comparison with Uralic second-person singular
*-t. Compare, within Indo-European itself,
*-s second-person singular injunctive,
*-si second-person singular present indicative,
*-tHa second-person singular perfect,
*-te second-person plural present indicative,
*tu "you" (singular) nominative,
*tei "to you" (singular) enclitic pronoun. These forms suggest that the underlying second-person marker in Indo-European may be
*t and that the
*u found in forms such as
*tu was originally an affixal particle or merely analogical. An Indo-European marginal locative
*-en compares in function the most closely with the Uralic locative
*-na, in form with the Uralic genitive
*-n, which has inspired suggestions of a single Indo-Uralic
*n-case with later development into multiple case forms in both families (Pedersen 1933) Similarities have long been noted between the verb conjugation systems of Uralic languages and Indo-European languages. Although it would not be uncommon for a language to borrow heavily from the
vocabulary of another language (as in the cases of
English from
French,
Persian from
Arabic, and
Korean from
Chinese), it would be extremely unusual for a language to borrow its basic system of verb conjugation from another. However, the strongly divergent sound systems of Proto-Indo-European and Proto-Uralic are an aggravating factor both in the morphological and the lexical realm, making it additionally difficult to judge resemblances and interpret them as either borrowings, possible cognates or chance resemblances.
Lexical A second type of evidence advanced in favor of an Indo-Uralic family is
lexical. A small number of words reconstructable to Proto-Indo-European and Proto-Uralic resemble each other (see list below). The problem is to distinguish between cognates and borrowings. Uralic languages have been in contact with a succession of Indo-European languages for millennia. As a result, many words have been borrowed between them, most often from Indo-European languages into Uralic ones. An example of a Uralic word that cannot be original is
Finno-Ugric *
śata "hundred". The Proto-Indo-European form of this word was (compare Latin ), which became in early
Indo-Iranian (reanalyzed as the neuter nominative–accusative singular of an
a stem > Sanskrit , Avestan ). This is evidence that the word was borrowed into Finno-Ugric from Indo-Iranian or
Indo-Aryan. This borrowing may have occurred in the region north of the
Pontic–Caspian steppes around 2100–1800 BC, the approximate
floruit of Indo-Iranian (Anthony 2007:371–411). It provides linguistic evidence for the geographical location of these languages around that time, agreeing with archeological evidence that Indo-European speakers were present in the Pontic-Caspian steppes by around 4500 BCE (the
Kurgan hypothesis) and that Uralic speakers may have been established in the
Pit-Comb Ware culture to their north in the fifth millennium BCE (Carpelan & Parpola 2001:79). Another ancient borrowing is Finno-Permic
*porćas "piglet". This word corresponds closely in form to the Proto-Indo-European word reconstructed as , attested by such forms as Latin "hog",
Old English (> English
farrow "young pig"),
Lithuanian "piglet, castrated boar", and
Saka pāsa ( Finno-Ugric *
-as) is a masculine nominative singular ending, but it is quite meaningless in Uralic languages. This shows that the whole word was borrowed as a unit and is not part of the original Uralic vocabulary. Thus, *
śata cannot be Indo-Uralic on account of its
phonology, while *
porćas cannot be Indo-Uralic on account of their
morphology. Such words as those for "hundred", "pig" 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", (compare English
cow) and "grain", (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. Advocates of a genetic relation between Indo-European and Uralic maintain that the borrowings can be filtered out by application of phonological and morphological analysis and that a core of vocabulary common to Indo-European and Uralic remains. As examples they advance such comparisons as Proto-Uralic : Proto-Indo-European , oblique stem , both meaning 'water', and Proto-Uralic : Proto-Indo-European , both meaning 'name'.
Objections to this interpretation It has been countered that nothing prevents this common vocabulary from having been borrowed from Proto-Indo-European into Proto-Uralic. For the old loans, it is more the rule than the exception that only the stem is borrowed, without any case-endings.
Proto-Uralic has been explained according to sound laws governing substitutions in borrowings (Koivulehto 1999), on the assumption that the original was a zero-grade oblique stem PIE as attested in later Balto-Slavic
*inmen- and Proto-Celtic .
Proto-Uralic could be a loan from the PIE oblique
e-grade form for 'water' or from an indirectly attested cognate root noun
*wed-. Proto-Uralic 'give' and PFU 'lead' also make perfect phonologic sense as borrowings. The number systems of Indo-European and Uralic show no commonalities. Moreover, while the numbers in all Indo-European languages can be traced back to reconstructed
Proto-Indo-European numbers, this cannot be done for the Uralic numbers, where only "two" and "five" are common to all of the family (roots for 3-6 are common to all subgroups other than Samoyedic, and slightly less widespread roots are known for numerals other than 8 and 9). This would appear to show that if Proto-Indo-European and Proto-Uralic are to be related, the connection must lie so far back that the families developed their number systems independently and did not inherit them from their purported common ancestor. Although, the fact that Uralic languages themselves do not share the same numbers across all Uralic branches indicates that they would not with Indo-European languages in any case, even if they were in fact related. It is also objected that some or all of the common vocabulary items claimed are
false cognates – words whose resemblance is merely coincidental, like English
bad and Persian (
bad). == Some possible cognates ==
