this short contribution consists into three short lexical notes about Hittite cuneiform writing. We will argue that the Luwoid adjective hassuwassa/i- is a ghost word, that the reading wi4 for the sign MI did not exist and should be eliminated from the syllabary, and finally that the only occurrence of an alleged Luwian neuter stem arkamman- should be considered instead as a Hittite common gender accusative singular.
