Reconstruction:Proto-Celtic/sādīti

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

Usually explained as a causative verb from the root Proto-Indo-European *sed- (“to sit”), whence also *sedeti (“to sit”), with unusual lengthened grade.^[1] This derivation requires that this long-vowel causative coexist with a regular o-grade causative *sodīti in Celtic.

Schrijver alternatively reconstructs *stādīti, a simple o-grade causative to an extension of Proto-Indo-European *steh₂- (“to stand”).^[2] For the dental extension, Schrijver compares Gothic 𐍂𐍉𐌳𐌾𐌰𐌽 (rōdjan) and Old Irish ráidid (“to speak”); if Kroonen is correct, the dental extension is *-dʰh₁eti.^[3] This etymology excludes Welsh gwahodd but instead allows a connection to Welsh ansawdd (“quality”) instead.
