Reconstruction:Proto-Italic/-ēd
Proto-Italic edit
Etymology edit
Shows clear influence from the o-stem masculine ablative singular ending -ōd, and possibly the adverb suffix could be an ablaut variant thereof. Alternatively, it might be possible to derive the suffix from Proto-Indo-European *-eh₁ (instrumental ending) with the -d secondarily gained via the influence of the ablative ending.[1]
