-ngwë

we

-ngwë "we", 1st person dual inclusive pronominal ending: "thou and I" (compare the exclusive dual form -mmë). Caringwë, "the two of us do" (VT49:16). One source lists the ending as "-inke > -inque" instead (VT49:51, 53, 57; "inke" was apparently Old Quenya). In an earlier pronoun table reproduced in VT49:48, the ending -ngwë is listed as an alternative to -lmë, which Tolkien at the time used as the plural inclusive ending (a later revision made it plural exclusive).
