The Slavic liquid metathesis refers to the phenomenon of metathesis of liquid consonants in the Common Slavic period in the South Slavic and West Slavic (specifically, Czech and Slovak) area. The closely related corresponding phenomenon of pleophony (also known as polnoglasie or full vocalization) occurred in parallel, in the East Slavic languages.
The change acted on syllables in which the Proto-Slavic liquid consonants *r and *l occurred in a coda position. The result of the change is dependent upon the phonological environment and accents, and it varies in different Slavic languages.
The change has been dated to the second half of the 8th century, before any Slavic languages were recorded in writing. Therefore, the change itself cannot be observed, but it can be inferred by comparing words in different Slavic languages. Evidence of the earlier state of affairs is also preserved in loanwords into and from Early Slavic as well as in cognates in other Indo-European languages, particularly Baltic languages.
During the Common Slavic period, a tendency, known as the law of open syllables, led to a series of changes that completely eliminated closed syllables. By the Old Church Slavonic period, every syllable, without exception, ended in a vowel. Some of the changes included the monophthongization of diphthongs, the loss of word-final consonants (OCS nebo < PIE *nébʰos), the simplification of some medial consonant clusters (OCS tonǫti < *topnǫti) and the formation of the nasal vowels *ǫ and *ę, respectively from *am/*an and *em/*en.
The change discussed here is part of this process, and it involved the liquid consonants, grouped under the cover symbol R, *l or *r in a coda position, in environments that are traditionally designated as in the table on the right. The application of the law of open syllables in such environments had different results in different Slavic dialects, and it is some of the earliest evidence for differentiation into the multitude of Slavic languages.
In some, it is the metathesis of a sequence of a liquid consonants followed by a vowel, and in others, it is an insertion of another vowel. In most cases, the effect was to eliminate the syllable-final consonants *l and *r so that the law of open syllables was maintained.

Metathesis then occurred in all Slavic dialects. In South Slavic dialects (Slovene, Serbo-Croatian, Macedonian, Bulgarian) as well in Czech and Slovak, the metathesized vowel was lengthened as well.
In East Slavic and the Lechitic branch of West Slavic, the outcome was dependent upon the Proto-Slavic accent: in acuted syllables, the output was the same as in South Slavic and Czech-Slovak, but on circumflexed syllables, the metathesized vowel did not lengthen.
|Area||Acuted syllable||Circumflexed syllable|
|South Slavic, Czech and Slovak||CS *oRT > CS *raT||PSl. *aRC > PSl. *RāC > CS *RaC||CS *oRT > CS *raT||PSl. *aRC > PSl. *RāC > CS *RaC|
|North Slavic||CS *oRT > CS *roT||PSl. *aRC > PSl. *RaC > CS *RoC|
Compare the following reflexes:
|Accent||Proto-Slavic reconstruction||South Slavic, Czech and Slovak||North Slavic|
|OCS||Slovene||Serbo-Croatian||Bulgarian||Macedonian||Czech||Slovak||Russian||Belarusian||Ukrainian||Polish||Low. Sorbian||Upp. Sorbian|
|Acute||PSl. *ardla > CS *őrdlo "plough"||ralo||rálo||rȁlo / ра̏ло||ра́ло (rálo)||рало (ralo)||rádlo||radlo||ра́ло (rálo)||ра́ла (rála)||ра́ло (rálo)||radło||radło||radło|
|Circumflex||PSl. *arstu > CS *orstъ "growth"||rastŭ||rȃst||rȃst / ра̑ст||ръст (răst)||раст (rast)||růst||rast||рост (rost)||рост (rost)||ріст (rist)||wzrost||róst|
If the syllable was not acuted, the metathesis in West and East Slavic occurred without the lengthening so EPSl. *a retains its short quantity and yields /o/; compare EPSl. *ȃlkuti ('elbow') > Serbo-Croatian lȃkat but Czech loket.
Word-medially, on the other hand, there were three primary outcomes:
As a result of dialect-specific changes occurring before and after the cluster resolution (metathesis/pleophony), the outcomes in various languages are diverse and complex. For example, in North-West Lechitic (northern Kashubian, Slovincian, Pomeranian and Polabian) and East Slavic, *CalC and *CelC merged into *CalC prior to cluster resolution:

If the liquid metathesis is complete only if it occurred with the corresponding vowel lengthening, the metathesis occurred completely in South Slavic and partially in Slovak and in non-word-initial position in the whole Czecho-Slovak area. The complete metathesis has been operational in all Slavic languages for acuted syllables. For word-initial non-acuted syllables, there was no lengthening except in South Slavic and, partially, Slovak.
As mentioned, the complete metathesis occurred in South Slavic, in Czech and Slovak and in Polish and Sorbian, without lengthening. In North-West Lechitic, the metathesis did not occur even for *CarC syllables. In East Slavic, pleophony yielded *CVRC > CVRVC. The reflex of *l in North-West Lechitic and East Slavic is always "hard".
Since the reflexes of acuted word-initial *ar- and *al- are the same in all Slavic dialects, they must have changed before the syllables ending with a liquid, which have different reflexes. One can thus distinguish the first and the second metathesis of liquids.
From Slavic evidence alone, the change cannot be dated precisely because no Slavic languages had yet committed to writing. However, words may have been documented from contemporary non-Slavic languages, and words may also have been borrowed into Slavic from other languages. That makes it possible to narrow down the time that the change occurred.
The liquid metathesis occurred in the Common Slavic era. It took place after or was still productive until the end of the 8th century. The name Charlemagne, who died in 814, underwent the change:
On the other hand, the change had already been completed in the earliest Old Church Slavonic documents. That implies that the change was completed, at least in the dialects of Bulgaria and of Macedonia, in no later than the 9th century, when the documents were written.
There are also glosses of Slavic words in foreign-language sources. Earlier sources show no effect of liquid metathesis, such as when the late-8th-century Greek chronicler Theophanes the Confessor writes Slavic names as Ἀρδάγαστος (Ardágastos) and Δαργαμηρός (Dargamērós). Old Church Slavonic versions of the names, with the metathesis applied, would be Radogostъ and Dragoměrъ. Liquid metathesis is also seen in various borrowings preserved in toponymics; Latin Arba > Serbo-Croatian Rȃb, Latin Albōna > Serbo-Croatian Làbīn, Latin Scardōna > Serbo-Croatian Skràdīn etc.
It has been suggested that East Slavic preserved the actual state of affairs, that the vowel was inserted in Common Slavic and that it was only subsequently lost in all dialects except in East Slavic, preceding the liquid. The exact development would thus be in Serbo-Croatian as follows:
