The word warnode occurs just nine times in Domesday Book, all in Kesteven in south Lincolnshire, all relating to obligations laying upon the woodland or meadow attached a manor. The associations of the term are uncertain. It may relate to wara, or defence obligations, that is the responsibility for paying geld and performing other duties incumbent upon land assessed for taxation and military service. Alternatively, it may have more local, Scandinavian associations.
There is a detailed discussion of this customary due in a note to the printed Phillimore text (LIN 2,36).
