Rhaeto-Romance, or Rhaetian, is a traditional subfamily of the Romance languages that is spoken in north and north-eastern Italy and in Switzerland. The name "Rhaeto-Romance" refers to the former Roman province of Rhaetia. The linguistic basis of the subfamily is discussed in the so-called Questione Ladina.
The area where Rhaeto-Romance languages (also called Ladin languages in a wider sense, not to be confused with Judaeo-Spanish) were spoken during the Middle Ages stretched from Switzerland to the Julian Alps (in modern-day western Slovenia).
The Rhaeto-Romance languages can be distinguished into the following varieties:
- Romansh: Switzerland. Romansh has status in Switzerland as a national language with three other national languages; however, its usage is rather limited to the canton of Graubünden (Romansh: Grischun). It is composed of the following dialects:
- Friulian: Friuli region, Italy
A phylogenetic classification using basic lexicon identifies a primary split between Romansh in Switzerland and Ladin in Italy. One secondary split distinguishes Engadinic from the other Romansh varieties in Switzerland. In Italy, another secondary split is evidently caused by the Dolomite mountain range that divides Ladin into a northern and a southern subbranch, with Friulian being grouped closest to the southern branch.
In this study, the divergence of the Rhaeto-Romance languages from their reconstructed lexical ancestor is about 7% on average. This would correspond to a time depth of about 500 years if the glottochronological replacement rate of 14% per millennium for Romance were trustworthy. However, the earliest available Romance text from the Alpine area is somewhat older and dates to AD1200.
The family is most closely related to its nearest neighbors: French, Franco-Provençal, Occitan, Gallo-Italian (Piedmontese, Ligurian, Lombard, Emiliano-Romagnolo), Venetian and Istriot. A number of lexical items are shared with Ibero-Romance due to the similar date of Latinization for both regions, although it can also be explained by means of Bartoli's areal linguistics theory, being Ibero-Romance a lateral area, as it is Balkano-Romance, Southern-Italian and Rhaeto-Romance, whereas Gallo-Romance and Italo-Romance are central area.
Before the Roman conquest, the Alps were Celtic-speaking in the north and Rhaetian-speaking in the south. The area was incorporated into the Roman Empire during the reign of Augustus. The Rhaeto-Romance languages originated as a dialect of the provincial Latin of the central Alps. By the end of the Roman Empire, there was an unbroken region of distinctive Romance speech here, which was gradually fragmented into secluded areas in the high valleys by the encroachment of German dialects from the north and of Gallo-Italic languages from the south.
Rhaeto-Romance is distinguished by a number of features that distinguish it from its neighbors, some of which it shares with French:
- diphthongization of Vulgar Latin open e into ei, closed e into ie
- Latin pede → Rom. (Surselvan) pei "foot", Lad pl. piesc "feet"
- Latin festa → Rom. (Surselvan) fiasta, Friul fieste "party, feast"
- occasional change of stressed a to e, particularly after a palatalized velar
- fronting of long ū in all stages ui → ü [y] → i
- Latin plūs "more" → Friul plui : Lad plü, Rom (Engadine) plü : Rom (other dialects) pli
- loss of final vowels except -a, which often weakens to -e (in Friulian there is also a feminine plural in -is)
- Rom. saira, Lad sëra, Friul sere "evening"
- Rom. festa, Lad festa, Friul fieste "party"
- general palatalization of the ca and ga groups
- Lad ciampana [tʃampana], Friul čhampane "bell" [tʃampane]
- preserved cl-, pl-, fl-; preserved Germanic w
- Latin clāvem → Rom clav/clev, Lad (Fascian, Fodom) kle(f), Friul clâf "key"
- Lat plēbs → Rom plaiv "parish", Lad plief "parish", Friul plêf "parish church"
- Lat flātus → Rom flad, Lad fle, fla, Friul flât "breath"
- Gothic werra → Rom (Surselvan) uiara, (Sutselvan) veara, Lad vera, Friul vuere "war"
- voicing of intervocalic unvoiced consonants
- loss of intervocalic voiced consonants
- preserved final -s leading to a single case based on an obsolete oblique that combined different endings from non-nominative cases; formerly a double case system.
