pightle pī'tl, (noun) a small enclosure: a croft.  A dialect word from Norfolk.  Its derivation is obscure but possibly dates from the nineteenth century.  In Norfolk, arable farming is of major importance.  Mechanical devices were introduced during the nineteenth century (e.g. for ploughing, harrowing, reaping, threshing and sowing).  Such devices were still horse-drawn but required fairly large rectangular fields.  Odd-shaped fields now caused problems which had not been encountered in the days before mechanisation.

Thus, over several years, fields were reorganised to be acceptably rectangular. This was cleverly and thoughtfully arranged but, inevitably, there were remnants, leftovers, off-cuts or tailings.  In most cases, these were small pieces of land, which were essentially triangular in shape.  The locals probably referred to these pieces as ‘pigtails’. In Norfolk dialect, this would quickly become pronounced as "pightle".  In the 1920's through the 1940's, the word pightle was in fairly common usage but has fallen into disuse in recent years.
