Drop

Drop an item (d)

       This drops an item from your inventory or equipment onto the
       dungeon floor.  If the floor spot you are standing on already has
       an object in it, Angband will attempt to drop the item onto an
       adjacent space.  Be warned that if the floor is full and you
       attempt to drop something, it may disappear and be destroyed.
       Doors and traps are considered objects for the purpose of
       determining if the space is occupied.  This command may take
       a quantity, and takes some energy.
