Wrong no of type of arguments for field called 'keywords'

CREATE OR REPLACE TRIGGER TRG_CORRESPONDENCE_UPT   AFTER UPDATE
  on TBLCORRESPONDENCE
  for each row

BEGIN

	IF  :OLD.Keywords <> :NEW.Keywords THEN
		spInsertAuditRecord_ins('tblCorrespondence',
			 'Keywords',


			 :OLD.CorrespondenceId,

			 :OLD.Keywords,


			 :NEW.Keywords,


			 SYSDATE,


			 :OLD.UpdatorId,


			 'U',
			 0);
	END IF;

END TRG_CORRESPONDENCE_UPT; /

I'm getting a 'wrong number of arguments or datatype' error message. If I replace the reference to 'keywords' with any other column name or literal, the trigger will compile. I cannot find any documentation in Oracle that states that 'keywords' is itself a keyword. Anybody got any ideas. You can respond to me directly at cherry.taylor_at_dhs.state.tx.us or to this post.
