". More certainly, very similar-looking alterations in the systems of long vowels in the West Germanic languages greatly postdate any possible notion of a proto-language innovation (and cannot readily be regarded as "areal", either, since English and continental West Germanic were not a linguistic area). In a similar vein, there are many similar innovations in Germanic and Balto-Slavic that are far more likely to be areal features than traceable to a common proto-language, such as the uniform development of a high vowel (*u in the case of Germanic, *i/u in the case of Baltic and Slavic) before the PIE syllabic resonants *?,* ?, *?, *?, unique to these two groups among IE languages. The Balkan sprachbund even features areal convergence that comprise very different branches.

" applies, featuring borrowings and no clear underlying genetic tree. Using an extension to the Ringe-Warnow model of language evolution early IE was confirmed to have featured limited contact between distinct lineages, while only the Germanic subfamily exhibited a less treelike behaviour as it acquired some characteristics from neighbours early in its evolution rather than from its direct ancestors. The internal diversification of especially West Germanic is cited to have been radically non-treelike.

Subgroupings of the Indo European languages are commonly held to reflect genetic relationships and linguistic change
Historical linguistics

Historical linguistics is the study of language change. It has five main concerns:* to describe and account for observed changes in particular languages;...
. The generic differentiation of Proto-Indo-European into dialects and languages happened hand in hand with language contact and the spread of innovations over different territories.

Rather than being entirely genetic, the grouping of satem languages is commonly inferred as an innovative change that occurred just once, and subsequently spread over a large cohesive territory or PIE continuum that affected all but the peripheral areas. For instance, Kortlandt proposes this satemization process involved interaction between a western and central Indo-European sphere of influence to the ancestors of Balts and Slavs.

Shared features of Phrygian and Greek and of Thracian and Armenian group the southeastern branches of Indo-European together. Some fundamental shared features, like the verbal aorist category (this is a verb form denoting action without reference to duration or completion) having the perfect active particle -s fixed to the stem, link this group closer to Anatolian languages and Tocharian. Shared features with Balto-Slavic languages, on the other hand (especially present and preterit formations), might be due to later contacts.

The Indo-Hittite
Indo-Hittite

In Indo-European linguistics, the term Indo-Hittite refers to Edgar H. Sturtevant's 1926 hypothesis that the Anatolian languages may have split off the Proto-Indo-European language considerably earlier than the separation of the remaining Indo-European languages....
 hypothesis proposes the Indo European language family to consist of two main branches: one represented by the Anatolian languages and another branch encompassing all other Indo European languages. Features that separate Anatolian from all other branches of Indo-European (such as the gender or the verb system) have been interpreted alternately as archaic debris or as innovations due to prolonged isolation. Points proffered in favour of the Indo-Hittite hypothesis are the (non-universal) Indo-European agricultural terminology in Anatolia and the preservation of laryngeals. However, in general this hypothesis is considered to attribute too much weight to the Anatolian evidence. According to another view the Anatolian subgroup left the Indo-European parent language comparatively late, approximately at the same time as Indo-Iranian and later than the Greek or Armenian divisions. A third view, especially prevalent in the so-called French school of Indo-European studies, holds that extant similarities in non-satem languages in general - including Anatolian - might be due to their peripheral location in the Indo-European language area and early separation, rather than indicating a special ancestral relationship. Holm (2008) based on lexical calculations arrives at a picture roughly replicating the general scholarly opinion and refuting the Indo-Hittite hypothesis.

, * (labiovelars), * (velars), and *; (palatovelars). Satem languages (Indo-Iranian and Balto-Slavic) lost the distinction between labiovelar and pure velar sounds, and at the same time assibilated the palatal velars. The Centum languages (Germanic, Italic, and Celtic), on the other hand, changed the palatal velars to be the same as pure velars.

Note that the terms "Centum" or "Satem" do not imply that Centum languages descend from a "proto-Centum" or that languages exhibiting Satem features descend from a "proto-Satem". Most modern scholars see the Satem sound change as an areal feature radiating outward from the central Indo-European language communities, but largely failing to reach the western and eastern peripheries.

Some scholars think that some languages classify neither as Satem nor as Centum (Anatolian, Tocharian, and possibly Albanian).

Areal contact among already distinct post-PIE languages (say, during the 3rd millennium BC) may have spread the sound changes involved. In any case, present-day specialists are rather less galvanized by the division than 19th cent. scholars were, partly because of the recognition that it is, after all, just one isogloss

, and the Proto-Pontic postulation of John Colarusso. Objections to such groupings are not based on any theoretical claim about the likely historical existence or non-existence of such super-families; it is entirely reasonable to suppose that they existed. The difficulty in identifying the details of actual relationships between language families, however, comes in finding concrete evidence that transcends chance resemblance. Since the noise-to-signal ratio in historical linguistics increases steadily over time, at great enough time-depths it becomes open to reasonable doubt that it can even be possible to distinguish between signal and noise.

s of periphrastic forms are in brackets when they appear. Some of these verbs have undergone a change in meaning as well.
  • In Modern Irish beir usually only carries the meaning to bear in the sense of bearing a child, its common meanings are to catch, grab.
  • The Hindi verb bharna, the continuation of the Sanskrit verb, can have a variety of meanings, but the most common is "to fill". It is conjugated periphrastically using a pronoun and an auxiliary.
  • In French, the irregular Latin verb ferre "to carry" has been supplanted by other verbs and ferre only survives in compounds such as souffrir "to suffer" (from Latin sub- and ferre) and "to confer" (from Latin "con-" and "ferre).
  • In Modern Greek, phero f??? (modern transliteration fero) "to bear" is still used but only in specific contexts not in everyday language. The form that is (very) common today is pherno f???? (modern transliteration ferno) meaning "to bring". Additionally, the perfective form of pherno (used for the subjuctive voice and also for the future tense) is also phero.
