For your first question I think they mean CLUE. "No one has a CLUE what powers this amulet brings." You did well getting the meaning right from the context! Using the word CLUE, is like saying "They have no IDEA what powers this amulet may bring." That sentence is okay, but it flows better like this. "No one has a clue(idea) what powers this amulet will bring." 1. Harvest the wheat fields. -Nothing wrong here- :) 2. Harvest the wheat in fields. -This one would sound better written "Harvest the wheat in THE fields." Without adding "the" it sounds less targeted and like something is missing. "This is a scythe of average quality but don't complain. It reaps and it's bloody well free. What else do you want?" -This sentence is basically saying, "this scythe is not the best, but it does it's job and it's cheap. What more could you ask for!" Hope that this will clear up all your questions! P.S. There is actually a neat story behind the word clue. I found this little snippet and thought I would post it for everyone since that is one of my favorite words. :) " The word ‘clue’ derives from ‘clew,’ meaning a ball of thread or yarn. It had come to mean ‘that which points the way’ because of the Greek myth in which Theseus uses a ball of yarn, given to him by Ariadne, to find his way out of the Minotaur’s labyrinth. The wirters of the mid-nineteenth century still had this image in mind when they used the word… . The thread that led Theseus out of the maze was true to another principle of Whicher’s investigation: the progress of a detective was backwards. To find his way out of danger and confusion, Theseus had to retrace his steps, return to the origin. The solution to a crime was the beginning as well as the end of a story.
