pretty sweet, paul

erik, you did say you wanted a query to return just those results, and
paul's query will do that very nicely -- i guess i was reading too much
into your questions, and assumed you'd be interested in a query to remove

note:  if you want any other columns besides word_id, it gets a little

in that case, try

   select word_id, word_value, word_type, word_date
     from thetable XX
   where word_id =
         ( select min(word_id)
               from thetable
            where word_value = XX.word_value )

the above assumes you are testing duplicates based on just word_value, and
are interested in only the row with the lowest id in that group
