English: habitational name from any of the numerous places so
called, which split more or less evenly into two groups with different
etymologies. One set (with examples in Berkshire, Dorset,
Gloucestershire, Hampshire, Herefordshire, Somerset, and Wiltshire) is
named from the Old English weak dative
hean (originally used
after a preposition and article) of
heah ‘high’ + Old
English
tun ‘enclosure’, ‘settlement’. The other (with
examples in Cambridgeshire, Dorset, Gloucestershire, Herefordshire,
Northamptonshire, Shropshire, Somerset, Suffolk, and Wiltshire) has
Old English
hiwan ‘household’, ‘monastery’. Compare
Hine as the first element.
