tala(no)ite
adjective. footed
An adjective appearing as talaite or talanoite “footed” in the Qenya Lexicon, an elaboration of ᴱQ. tala “foot” (QL/88).
Neo-Quenya: Since -itë remains an adjective suffix in Tolkien’s later conception of the language, I think ᴺQ. talaitë “footed” can be retained for purposes of Neo-Quenya, analogous to Q. maitë “handed”.
tatto
noun. father
yúyo
cardinal. two
An archaic dvanda dual form in the Early Qenya Grammar of the 1920s referring to both parents based on older atta(h)-, replaced by the dual atarqi of ᴱQ. atar in normal speech (PE14/77). As a dvanda dual, it was based on the word for “father”, with “mother” being implied. It also appeared in an (archaic?) plural form attahi in the English-Qenya Dictionary, but presumably this only meant “fathers” (PE15/72).
