This Proto-Slavic entry contains reconstructed words and roots. As such, the term(s) in this entry are not directly attested, but are hypothesized to have existed based on comparative evidence.



Based on comparison between the adjective form *dǫbrъ and Proto-Germanic *timrą (timber), Lithuanian dum̃blas (swamp), it appears that the etymon descends from a Caland's root (probably Proto-Indo-European *dem- (to build)). The exact etymology, however, is uncertain.

The etymon is attested both as an o-stem and as a u-stem, but per Vasmer, the original more likely was u-stem.
