Descendants

The ā-stems of Baltic may be remnants of the original plural, reanalysed as singulars. The acute found in these languages may be an (East) Baltic innovation; Slavic offers no evidence either way due to Meillet's law.

East Baltic:
- Latvian: dar̂va (“tar”)
- Lithuanian: dervà (“tar, resin”)
Proto-Slavic: *dȇrvo (see there for further descendants)
→ Proto-Finnic: *tërva
