Edgerton

The most ambitious extension of Sievers' law was proposed by Franklin Edgerton (1885–1963) in a pair of articles in the journal Language

( and ). He argued that not only was the syllabicity of prevocalic semivowels by context applicable to all six Indo-European semivowels , it was applicable in all positions in the word. Thus a form like "sky" would have been pronounced like this only when it happened to follow a word ending with a short vowel. Everywhere else it would have had two syllables, .

 suvīra-). According to Edgerton, the word should have had two forms, depending on what immediately preceded it: and . This corollary he called the "converse" to Sievers' law, and is usually referred to as Edgerton's converse for short.

The evidence for alternation presented by Edgerton was of two sorts. He cited several hundred passages from the Rigveda, which he claimed should be rescanned to reveal hitherto unnoticed expressions of the syllable structure called for by his theory. But most forms show no such direct expressions; for them, Edgerton noted sharply skewed distributions that he interpreted as evidence for a lost alternation between syllabic and nonsyllabic semivowels. Thus say śiras "head" (from ) has no monosyllabic partner **śras (from ), but Edgerton noted that it occurred 100% of the time in the environments where his theory called for the syllabification of the .

 with the loss of the form itself. And he was able to present a sizeable body of evidence in the form of these skewed distributions in both the 1934 and 1943 articles.

Edgerton's claims were immediately hailed by many in the scholarly community and enjoyed the status of orthodoxy among Indo-Europeanists for 35 or 40 years; in recent times they have not fared so well.

Parenthetically, many of Edgerton's data on this point are inappropriate: current scholarship takes śiras, for example, to be the regular reflex of PIE , the syllabicity of the resonant resulting from the fact that it was followed by a consonant in Proto-Indo-European; there never was, nor could have been, a form to yield Indic **śras. How it might be that a form that is irrelevant to Edgerton's theory might seem to "behave" in accord with it is explained below.

 (1936–) published an article proposing a significant modification of Edgerton's theory. Disregarding Edgerton's evidence (on the grounds that he was not prepared to judge the niceties of Rigvedic scansion) he took instead as the data to be analyzed the scansions in Hermann Grassmann

's Wörterbuch zum Rig-Veda . From these he concluded that Edgerton had been right, but only up to a point: the alternations he postulated did indeed apply to all semivowels; but in word-initial position, the alternation was limited to forms like "sky", as cited above – that is, words where the "short" form was monosyllabic.

Newer developments

Edgerton's claims, once very generally hailed, have not fared well. Regarding the skewed distributions in the Rigveda, Edgerton neglected to test his observations against controls

 configuration, and so on. The first scholar to look at controls was Franklin Eugene Horowitz . Horowitz noted that for example all 65 occurrences of Vedic suvīra- "well-heroed" do occur in line-initial position or follow a heavy syllable (as if in accord with Edgerton's converse), but exactly the same thing is true of e.g. supatrá- "having beautiful wings" (which can have nothing to do with Edgerton's law). And indeed such skewing in distribution is pervasive in Vedic vocabulary: śatam "100", and dozens of other forms with no bearing on Edgerton's law, have exactly the same strong preference for not following a word ending with a short vowel that e.g. śiras "head" does, presumably by reason of beginning with a single consonant followed by a light syllable.

A second difficulty has emerged much more recently : The actual passages from the Rigveda cited in Edgerton's two large articles in 1934 and 1943 as examples of the effects of his theory in action seriously misrepresent the facts in all but a handful of cases. No more than three Rigvedic passages cited in the 1934 article, and none at all in 1943, actually support the claims of Edgerton's law regarding word-initial sequences. This lies well within the operation of pure chance. And it has been shown also that the apparent success of Lindeman's more modest claims are not without troubling problems, too, such as the limitation of the reliable examples to vocalic semivowels (the glides and ) even though such alternations in the other four semivowels should have left robust outcomes (for example, a disyllabic form of prá "forth, away" should have been very much more frequent than the monosyllable, which would have occurred only after a word ending in a short vowel; but there is no evidence for such a disyllabic form, in Vedic or any other form of Indic); and that the syllabified alternants (e.g. ) are very much rarer than they should be: they account for only fifteen to twenty percent of the total: they should account for at least eighty percent, since the monosyllabic form would have originally occurred, like prá, only after a word ending in a short vowel. Further, only the alternants have a "distribution": the shapes show no sensitivity to phonetic environment at all. (And even that disyllabic "distribution" can be inexplicable: disyllabic dyāus in the Rigveda always and only, with one exception, occurs in line-initial position, i.e., in only one of the four environments calling for syllabification of the resonant. Nothing in Lindeman's theory accounts for this striking distribution.)

Sievers' law in Germanic

Within the context of Indo-European, Sievers' law is generally held to be one-way. That is, it applied only to create syllabic resonants from nonsyllabics after heavy syllables, but not the other way around after light syllables. In Proto-Germanic, however, the law came to be applied in both directions, with PIE syllabic becoming nonsyllabic after light syllables. As a consequence, suffixal -j- and -ij- came to be in complementary distribution in Proto-Germanic, and were perceived as allophonic variants of the same suffix. Following the loss of j before i, -ī- was also complementary to -i- (from earlier -iji- and -ji- respectively) in inflected forms of words that had -ij- and -j- otherwise.

The alternation is preserved in many of the older languages. In Gothic, for example, although the alternant -ij- is consistently spelled -j-, the contraction of *-jaz in final syllables yields -jis while *-ijaz yields -eis (that is, -īs). In Old Norse, nonsyllabic -j- is preserved, but syllabic -ij- is lost. This is seen in class 1 weak verbs, which end in -ja (from Germanic *-janaN) following a short stem, but in -a (from Germanic *ijanaN) following a long stem. Word-finally, the distribution is reversed, as in neuter ja-stem nouns with syllabic -i (from *-ijaN) after long stems but no ending (from *-jaN) after short stems. The West Germanic languages such as English largely lost the alternation because of the effects of the West Germanic gemination
West Germanic Gemination

, but the gemination itself was conditioned only by -j- and not by -ij-, so that the alternation is indirectly preserved.

It has been argued that Sievers' law is actually an innovation of Germanic. The syllabic shape is found not only after heavy syllables, as in Vedic, but also after some polysyllabic stems. This is quite unlike anything in Indic. More significantly, the conditions for the alternation are specifically Germanic, not Proto-Indo-European. Thus Proto-Germanic *wurkīþi "(s)he works", *wurkijanþi "they work" (Gothic waurkeiþ /workīþ/, waurkjand) and *satiþi "(s)he sets", *satjanþi "they set" (Gothic satjiþ, satjand), with Sievers' distributions in good order. But the forms in their Proto-Indo-European shape were , and , respectively, which should have resulted in **wurkiþi, **wurkjanþi and **satīþi, **satijanþi. However, the regular Germanic evolution of *ur from made a light root

 syllable heavy; the Germanic change of to *-ī- ( in unstressed syllables regularly became *i) set the stage for the truncation of inherited (intermediate) *satijiþi to Sievers' proto-form *satjiþi, which finally became *satiþi. In other words, not only are Proto-Indo-European structures not needed to account for the facts of Germanic, they actually get in the way.

    "; therefore the objection concerning PIE vs. Proto-Germanic *wurkīþi is not valid. That is, Sievers' law was not a sound change that took place at some particular time, but rather a phonological law that remained in the grammar of the language over time and operated on the output of various phonological processes. When PIE changed to *ur in Proto-Germanic, Sievers' law automatically changed forms such as to .
  2. The converse of Sievers' law – which changes to after a light syllable – was indeed a Germanic innovation that did not apply to PIE. Essentially, Proto-Germanic inherited Sievers' law from PIE and then extended it to apply in both directions. This answers the concern about *satiþi vs. .
  3. The extension of the Sievers'-law variant to polysyllabic as well as heavy-syllable stems was another Germanic innovation.


Sievers' law in Germanic was clearly conditioned on morphological grounds as well as phonological, since suffixes were treated as separate words if they were recognised as separate morphological segments. For example, the suffix *-atjanaN had a nonsyllabic -j- because the preceding -at- was light, as in Old English -ettan, where the gemination

is evidence for -j-. On the other hand, *-ārijaz had -ij- because the syllable -ār- was heavy, as in Gothic -areis, which would have been *-arjis if the suffix had contained -j- instead. This happened even though in fully formed words these -j- and -ij- would have been preceded by two syllables. Examples of the opposite - that is, multiple-syllable stems that were not segmentable - can also be found. *hamiþijaN ("shirt") clearly contained -ij-, showing that *hamiþ- in its entirety was analysed as the stem, rather than just *-iþ- since there was no such suffix in Proto-Germanic. This is evidenced by the Old High German hemidi, where *hemiddi would be expected if the original form had -j-.
