Reconstruction notes
Various tentative forms are given below to account for the descendants, many of which seem to have incorporated a dual suffix. Huehnergard reconstructs the lemma as *ṯin(ā)- to reflect both the Akkadian and West Semitic roots. Testen reconstructs *ṯn-, with an initial consonant cluster, which accounts for the r forms in Aramaic and Modern South Arabian.
