atta
cardinal. two
atta (1) cardinal "two" (AT(AT), Letters:427, VT42:26, 27, VT48:6, 19). Elen atta "two stars" (VT49:44); notice how a noun is indeclinable before this numeral, and any case endings are "singular" and added to the numeral rather than the noun, e.g. genitive elen atto "of two stars" (VT49:45). Attalyar "Bipeds" (sg. *Attalya) = Petty-dwarves (from Sindarin Tad-dail) (WJ:389). A word atta_ "again" was struck out; see the entry _TAT in Etym and cf. ata in this list.
atyo
noun. *daddy
satto
cardinal. two
satto, "Qenya" numeral "two" (in Tolkiens later Quenya atta) (VT49:54)
An affectionate address from 4-year old Ancalimë to her father Aldarion, in the 1st sg. possessive form tatanya (UT/191). It appears nowhere else, and I recommend using the better attested Q. atya for “my father (affectionate)”.
