Internal reconstruction

From Wikipedia, the free encyclopedia

Internal reconstruction is a method of reconstructing an earlier state in a language's history using only language-internal evidence of the language in question. [1]

The comparative method compares variations between languages, such as in sets of cognates, under the assumption that they descend from a single proto-language, but internal reconstruction compares variant forms within a single language under the assumption that they descend from a single, regular form. For example, they could take the form of allomorphs of the same morpheme.

The basic premise of internal reconstruction is that a meaning-bearing element that alternates between two or more similar forms in different environments was probably once a single form into which alternation has been introduced by the usual mechanisms of sound change and analogy. [2][ better source needed]

Language forms that are reconstructed by internal reconstruction are denoted with the pre- prefix, as in Pre-Old Japanese, like the use of proto- to indicate a language reconstructed by means of the comparative method, as in Proto-Indo-European. (However, the pre- prefix is sometimes used for an unattested prior stage of a language, without reference to internal reconstruction.) [3]

It is possible to apply internal reconstruction even to proto-languages reconstructed by the comparative method. For example, performing internal reconstruction on Proto-Mayan would yield Pre-Proto-Mayan. In some cases, it is also desirable to use internal reconstruction to uncover an earlier form of various languages and then submit those pre- languages to the comparative method. Care must be taken, however, because internal reconstruction performed on languages before the comparative method is applied can remove significant evidence of the earlier state of the language and thus reduce the accuracy of the reconstructed proto-language.

Role in historical linguistics

When undertaking a comparative study of an underanalyzed language family, one should understand its systems of alternations, if any, before one tackles the greater complexities of analyzing entire linguistic structures. For example, Type A forms of verbs in Samoan (as in the example below) are the citation forms, which are in dictionaries and word lists, but in making historical comparisons with other Austronesian languages, one should not use Samoan citation forms that have missing parts. (An analysis of the verb sets would alert the researcher to the certainty that many other words in Samoan have lost a final consonant.)

In other words, internal reconstruction gives access to an earlier stage, at least in some details, of the languages being compared, which can be valuable since the more time has passed, the more changes have been accumulated in the structure of a living language. Thus, the earliest known attestations of languages should be used with the comparative method.[ citation needed]

Internal reconstruction, when it is not a sort of preliminary to the application of the comparative method, is most useful if the analytic power of the comparative method is unavailable.[ citation needed]

Internal reconstruction can also draw limited inferences from peculiarities of distribution. Even before comparative investigations had sorted out the true history of Indo-Iranian phonology, some scholars had wondered if the extraordinary frequency of the phoneme /a/ in Sanskrit (20% of all phonemes together, an astonishing total) might point to some historical fusion of two or more vowels. (In fact, it represents the final outcome of five different Proto-Indo-European syllabics whose syllabic states of /m/ and /n/ can be discerned by the application of internal reconstruction.) However, in such cases, internal analysis is better at raising questions than at answering them. The extraordinary frequency of /a/ in Sanskrit hints at some sort of historical event but does not and cannot lead to any specific theory.

Issues and shortcomings

Neutralizing environments

One issue in internal reconstruction is neutralizing environments, which can be an obstacle to historically correct analysis. Consider the following forms from Spanish, spelled phonemically rather than orthographically:

Infinitive Third person singular
bolbér (re)turn buélbe
probár test pruéba
dormír sleep duérme
morír die muére
ponér place póne
doblár fold dóbla
goθár enjoy góθa
korrér run kórre

One pattern of inflection shows alternation between /o/ and /ue/; the other type has /o/ throughout. Since those lexical items are all basic, not technical, high-register or obvious borrowings, their behavior is likely to be a matter of inheritance from an earlier system, rather than the result of some native pattern overlaid by a borrowed one. (An example of such an overlay would be the non-alternating English privative prefix un- compared to the alternating privative prefix in borrowed Latinate forms, in-, im, ir-, il-.)

One might guess that the difference between the two sets can be explained by two different native markers of the third-person singular, but a basic principle of linguistic analysis is that one cannot and should not try to analyze data that one does not have. Also, positing such a history violates the principle of parsimony ( Occam's Razor) by unnecessarily adding a complication to the analysis whose chief result is to restate the observed data as a sort of historical fact. That is, the result of the analysis is the same as the input. As it happens, the forms as given yield readily to real analysis and so there is no reason to look elsewhere.

The first assumption is that in pairs like bolbér/buélbe, the root vowels were originally the same. There are two possibilities: either something happened to make an original */o/ turn into two different sounds in the third-person singular, or the distinction in the third-singular is original and the vowels of the infinitives are in what is called a neutralizing environment (if an original contrast is lost because two or more elements "fall together", or coalesce into one). There is no way of predicting when /o/ breaks to /ué/ and when it remains /ó/ in the third-person singular. On the other hand, starting with /ó/ and /ué/, one can write an unambiguous rule for the infinitive forms: /ué/ becomes /o/. One might notice further, upon looking at other Spanish forms, that the nucleus /ue/ is found only in stressed syllables even other than in verb forms.

That analysis gains plausibility from the observation that the neutralizing environment is unstressed, but the nuclei are different in stressed syllables. That fits with vowel contrasts often being preserved differently in stressed and unstressed environments and that the usual relationship is that there are more contrasts in stressed syllables than in unstressed ones since previously-distinctive vowels fell together in unstressed environments.

The idea that original */ue/ might fall together with original */o/ is unproblematic and so internally, a complex nucleus *ue can be reconstructed that remains distinct when it is stressed and coalesces with *o when it is unstressed.

However, the true history is quite different: there were no diphthongs in Proto-Romance. There was an *o (reflecting Latin ŭ and ō) and an (reflecting Latin ŏ). In Spanish, as in most other Romance languages, the two fall together in unstressed syllables, but breaks into the complex nucleus /ue/ in stressed syllables. Internal reconstruction accurately points to two different historical nuclei in unstressed /o/ but gets the details wrong.

Shared innovations

When applying internal reconstruction to related languages prior to applying the comparative method, one must check that the analysis does not remove the shared innovations that characterize subgroups. An example is consonant gradation in Finnish, Estonian, and Sami. A pre-gradation phonology can be derived for each of the three groups by internal reconstruction, but it was actually an innovation in the Finnic branch of Uralic, rather than the individual languages. Indeed, it was one of the innovations defining that branch. That fact would be missed if the comparanda of the Uralic family included as primary data the "degraded" states of Finnish, Estonian, and Sami. [4] [5]

Lost conditioning factors

Not all synchronic alternation is amenable to internal reconstruction. Even if a secondary split (see phonological change) often results in alternations that signal a historical split, the conditions involved are usually immune to recovery by internal reconstruction. For example, the alternation of voiced and voiceless fricatives in Germanic languages, as described in Verner's law, cannot be explained only by examining the Germanic forms themselves.

Despite that general characteristic of secondary split, internal reconstruction can occasionally work. A primary split is, in principle, recoverable by internal reconstruction whenever it results in alternations, but later changes can make the conditioning irrecoverable.

Examples

English

English has two patterns for forming the past tense in roots ending in apical stops: /t d/.

Type I
Present Past
adapt adapted
fret fretted
greet greeted
note noted
reflect reflected
regret regretted
rent rented
wait waited
waste wasted
abide abided
blend blended
end ended
found founded
fund funded
grade graded
plod plodded
Type II
Present Past
cast cast
cut cut
put put
set set
meet met
bleed bled
read /reed/ read /red/
rid rid
shed shed
bend bent
lend lent
send sent

Although Modern English has very little affixal morphology, its number includes a marker of the preterite, other than verbs with vowel changes of the find/found sort, and almost all verbs that end in /t d/ take /ɪd/ as the marker of the preterite, as seen in Type I.

Can any generalizations be made about the membership of verbs in Types I and II? Most obviously, the Type II verbs all end in /t/ and /d/, but that is just like the members of Type I. Less obviously, they are all basic vocabulary. That this is a claim about Type II verbs and not a claim about basic vocabulary since there are basic home-and-hearth verbs in Type I also. However, no denominative verbs (those formed from nouns like to gut, to braid, to hoard, to bed, to court, to head, to hand) are in Type II. There are no verbs of Latin or French origin (the latter is harder to notice); all stems like depict, enact, denote, elude, preclude, convict are Type I. Furthermore, all new forms are inflected as Type I and so all native speakers of English would presumably agree that the preterites of to sned and to absquatulate would most likely be snedded and absquatulated.

That evidence shows that the absence of a "dental preterite" marker on roots ending in apical stops in Type II reflects a more original state of affairs. In the early history of the language, the "dental preterite" marker was in a sense absorbed into the root-final consonant when it was /t/ or /d/, and the affix /ɪd/ after word-final apical stops then belonged to a later stratum in the evolution of the language. The same suffix was involved in both types but with a 180° reversal of "strategy." Other exercises of internal reconstruction would point to the conclusion that the original affix of the dental preterites was /Vd/ (V being a vowel of uncertain phonetics). A direct inspection of Old English would cetainly reveal several different stem-vowels involved. In modern formations, stems that end in /t d/ preserve the vowel of the preterite marker. As oddly as it might seem, the loss of the stem vowel had taken place already whenever the root ended in an apical stop before the first written evidence.

Latin

Latin has many examples of "word families" showing vowel alternations. Some of them are examples of Indo-European ablaut: pendō "weigh", pondus "a weight"; dōnum "gift", datum "a given", caedō "cut" perf. ce-cid-, dīcō "speak", participle dictus, that is, inherited from the proto-language (all unmarked vowels in these examples are short), but some, involving only short vowels, clearly arose within Latin: faciō "do", participle factus, but perficiō, perfectus "complete, accomplish"; amīcus "friend" but inimīcus "unfriendly, hostile"; legō "gather", but colligō "bind, tie together", participle collectus; emō "take; buy", but redimō "buy back", participle redemptus; locus "place" but īlicō "on the spot" (< *stloc-/*instloc-); capiō "take, seize", participle captus but percipiō "lay hold of", perceptus; arma "weapon" but inermis "unarmed"; causa "lawsuit, quarrel" but incūsō "accuse, blame"; claudō "shut", inclūdō "shut in"; caedō "fell, cut", but concīdō "cut to pieces"; and damnō "find guilty" but condemnō "sentence" (verb). To oversimplify, vowels in initial syllables never alternate in this way, but in non-initial syllables, but short vowels of the simplex forms become -i- before a single consonant and -e- before two consonants; the diphthongs -ae- and -au- of initial syllables alternate respectively with medial -ī- and -ū-.

As happened here, reduction in contrast in a vowel system is very commonly associated with position in atonic (unaccented) syllables, but Latin's tonic accent of reficiō and refectus is on the same syllable as simplex faciō, factus, which is true of almost all of the examples given (cólligō, rédimō, īlicō (initial-syllable accent) are the only exceptions) and indeed for most examples of such alternations in the language. The reduction of contrast points in the vowel system (-a- and -o- fall together with -i- before a single consonant, with -e- before two consonants; long vowels replace diphthongs) must not have had anything to do with the location of the accent in attested Latin.

The accentual system of Latin is well-known, partly from statements by Roman grammarians and partly from agreements among the Romance languages on the location of tonic accent: the tonic accent in Latin fell three syllables before the end of any word with three or more syllables unless the second-last syllable (called the penult in classical linguistics) was "heavy" (contained a diphthong or a long vowel or was followed by two or more consonants). Then, that syllable had the tonic accent: perfíciō, perféctus, rédimō, condémnō, inérmis.

If there is any connection, between word-accent and vowel-weakening, the accent in question cannot be that of Classical Latin. Since the vowels of initial syllables do not show that weakening (to oversimplify a bit), the obvious inference is that in prehistory, the tonic accent must have been an accent that was always on the first syllable of a word. Such an accentual system is very common in the world's languages ( Czech, Latvian, Finnish, Hungarian, and, with certain complications, High German and Old English) but was definitely not the accentual system of Proto-Indo-European.

Therefore, on the basis of internal reconstruction within Latin, a prehistoric sound-law can be discovered that replaced the inherited accentual system with an automatic initial-syllable accent, which itself was replaced by the attested accentual system. As it happens, Celtic languages also have an automatic word-initial accent that is subject, like the Germanic languages, to certain exceptions, mainly certain pretonic prefixes. Celtic, Germanic and Italic languages share some other features as well, and it is tempting to think that the word-initial accent system was an areal feature, but that would be more speculative than the inference of a prehistoric word-initial accent for Latin specifically.

There is a very similar set of givens in English but with very different consequences for internal reconstruction. There is pervasive alternation between long and short vowels (the former now phonetically diphthongs): between // and /ɪ/ in words like divide, division; decide, decision; between // and /ɒ/ in words like provoke, provocative; pose, positive; between // and /ʌ/ in words like pronounce, pronunciation; renounce, renunciation; profound, profundity and many other examples. As in the Latin example, the tonic accent of Modern English is often on the syllable showing the vowel alternation.

In Latin, an explicit hypothesis could be framed on the location of word-accent in prehistoric Latin that would account for both the vowel alternations and the attested system of accent. Indeed, such a hypothesis is hard to avoid. By contrast, the alternations in English point to no specific hypothesis but only a general suspicion that word accent must be the explanation, and that the accent in question must have been different from that of Modern English. Where the accent used to be and what the rules, if any, are for its relocation in Modern English cannot be recovered by internal reconstruction. In fact, even the givens are uncertain: it is not possible to tell even whether tonic syllables were lengthened or atonic syllables were shortened. (Actually, both were involved.)

Part of the problem is that English has alternations between diphthongs and monophthongs (between Middle English long and short vowels, respectively) from at least six different sources, the oldest (such as in write, written) dating all the way back to Proto-Indo-European. However, even if it were possible to sort out the corpus of affected words, sound changes after the relocation of tonic accent have eliminated the necessary conditions for framing accurate sound laws. It is actually possible to reconstruct the history of the English vowel system with great accuracy but not by internal reconstruction.

In short, during the atonic shortening, the tonic accent was two syllables after the affected vowel and was later retracted to its current position. However, words like division and vicious (compare vice) have lost a syllable in the first place, which would be an insuperable obstacle to a correct analysis.
