Knap
- usually denoting a hillock or knoll in Scots, this term comes into use in place-names by a variety of different routes as it has parallels in many different languages. Hills called knap may be derived from either Old English cnæpp 'top, summit' or Gaelic cnap 'knob', which may itself be a borrowing from Old Norse knappr 'knob, rounded top'. A well-known literary example is Peesie's Knap in Lewis Grassic Gibbon's Sunset Song (1932), where the first part of the name is the Scots word peesie 'lapwing'.
