An adjective appearing as cadwor, cadwar in The Etymologies of the 1930s derived from primitive ᴹ✶katwārā “shapely” (Ety/KAT). The variant forms likely had to do with whether or not ā remained long or was shortened in the final syllable of the primitive form; if it remained long then [[os|ā > ō [ǭ] > au]] [cadwaur with usual soft-mutation of t > d] and then au became o in the polysyllable, producing cadwor.
Conceptual Development: The Early Noldorin Grammar of the 1920s had an untranslated adjective ᴱN. {cadeg >>} cadog that might have a similar meaning (PE13/125).
cantëa ("k") ordinal "fourth" (VT42:25)
