A noun translated as “expression, saying, word” (SD/427). It is likely derived from the Primitive Adûnaic root √BITH “say” (SD/416). This word is very similar to Sindarin peth “word”, especially in the Sindarin lenited form beth. The ancient development of the Adûnaic word may have been similar to Sindarin, with Primitive Elvish root ᴹ√KWET > *√PET > ✶Ad. √BITH, as suggested by Helge Fauskanger (AL/Adûnaic).
