An adjective meaning “double” derived from the primitive root for two: ᴹ√AT (Ety/AT(AT)). The entry includes both intermediate and final forms adu and ado. Its Quenya cognate atwa indicates a primitive form ✱✶atwā, so this word is the clearest evidence that [[ilk|final [w] became [u]]] and [[ilk|final [u] became [o]]] in Ilkorin.
