If you?ve been puzzled by what your Texan (or Oklahoman) friends mean by a tin horn, or baffled by whether strubbly hair is a new style popular in Pennsylvania, or left wondering if you should be offended when a Mainer calls you a tunklehead, the fifth and final volume of the Dictionary of American Regional English (DARE) is here to set you straight. From it you?ll learn that a tin horn is a metal culvert, that strubbly hair is untidy or straggly, and that tunklehead is not a term of endearment.
