Proto-Romance is the result of applying the comparative method to reconstruct the latest common ancestor of the Romance languages. To what extent, if any, such a reconstruction reflects a real état de langue is controversial. The closest real-life counterpart would have been (vernacular) Late Latin.
Metaphony, if it can be projected back to Proto-Romance, may have initially been limited to open syllables. That is, it would have targeted allophonically lengthened /ɛɔ/.[4]
The forms below are spelt as they are in the cited sources, either in Latin style or in phonetic notation. The latter may not always agree with the phonology given above.
Some nouns of the –C type had inflections with alternating stress or syllable count:[19]

Gloss

There were also ‘neuter’ nouns. In the singular they would have been treated as masculine and in the plural as feminine, often with a collective sense.[20]
For the most part, the typical way to form a comparative would have been to add magis or plus (‘more’) to a positive adjective. A few words can be reconstructed as having a comparative ending -ior, which would have been inflected as follows:[21]
^That is, when followed by a syllable containing a close vowel.
^Diachronically this reflects the ‘weakening’ of vowels in this context, for which see Lausberg 1970:§§292–6. An example, per the latter, is Latin dormītorium > French dortoir.
^In representing it as such this article follows Burger 1955 and Petrovici 1956. Similarly, van den Bussche 1985 proposes a Proto-Romance consonant inventory with /ʎʎ ɲɲ (t)tʲ (d)dʲ (k)kʲ (ɡ)ɡʲ/ (p. 226) and Pope 1952 reconstructs Proto-Gallo-Romance with a series of palatalized consonants (§168). Gouvert 2015 prefers a phonetic palatalization rule for Proto-Romance, as in /basiˈare/ [baˈsʲaːɾe] (p. 83).
^Gouvert assumes regular (phonetic) gemination of palatalized intervocalic /n l k/ to [ɲɲ ʎʎ cc]. Repetti points out that there exists (mixed) Romance evidence for the gemination of all consonants in this context other than original /s/.
^Example from Gouvert. Per Lausberg the prop-vowel would have been added only after a consonant or pause.
^Diachronically this reflects the development of Latin intervocalic [b] to [β], and likewise [bj] to [βj], for which see Lausberg 1970:§§366, 475.
^de Dardel & Gaeng (1992:104) differ from Lausberg on the following points: 1) They believe that the genitive-dative case was limited to animate nouns. 2) They reconstruct a universal gen-dat. plural ending -orum. 3) They reconstruct, for class -a type nouns, a nominative plural -ae, albeit one in competition with -as according to de Dardel & Wüest (1993:57). They are in agreement with Lausberg regarding the remaining inflections.
