>> 101 phonological systems
Welcome to the DiaLS Database
The name DiaLS stands for Diachronic Language structures, as the DiaLS database targets hypotheses about
the structural properties of reconstructed proto-languages.
Language structure databases abound at the synchronic level. For example, the
the phonological inventories of a representative sample of the worls’ languages (now expanded to other phonological
properties in LapSyd
database surveys other structural (phonological,
grammatical, lexical) properties of language, and the LLCAN databases survey
. This list is not exclusive but
shows the widespread effort, at the synchronic level, for extended surveys of linguistic phenomena. No such effort has
been made -to our knowledge- for reconstructed protolanguages, and DiaLS aims to fill the gap.
DiaLS has a major role to play for the interpretation of the sound changes compiled in UniDia as it set them in the
systemic context of the (proto-)language. Coupled with UPSID, DiaLS will allow us to sketch the chain of influence
between the systems of the protolanguage and of its daughters and the sound changes that are assumed to have happened.
Moreover, it will enable to expand the models of change to the implicational tendencies in terms of other structural
features, both in the protolanguages and in their descendants.
DiaLS consists of separate but associated sections, each corresponding to a type of reconstructed structural properties.
So far, we have mainly been working on BDPROTO, which surveys the composition of the phonological systems posited for
reconstructed protolanguages. As in UniDia, the diverging transcription symbolisms are harmonized to the

We’ve tried to make the browsing as intuitive as possible, but if you think otherwise, we would like to have your feedback.
All sections are reachable through the left hand menu bar. For now, the public access mode only enables you to have an
overview of the database and a list of the bibliographical references used. To participate, please contact us through
