-tyë

you

-t (3) reduced pronominal affix of the 2. person, "you" (sg.), the long form being -tyë (both endings are listed in VT49:48). See heca regarding the example hecat (WJ:364). However, in a later source, Tolkien denies that -tyë has any short form (VT49:51, 57). The status of the ending -t is therefore doubtful.
