-lyë

you, thou

-l or -lyë (VT49:48, 51), pronominal endings for 2nd person sg. polite/formal "you, thou": caril or carilyë *"you do" (VT49:16), hamil "you judge" (VT42:33), anel "you were" (see #1); see -lyë for further examples. These endings may also be added to pronouns (etel/etelyë or mil, milyë; see et, mi). In one source, -l is rather used as a reduced affix denoting plural "you"; see heca! (WJ:364)
