_Hyrne_ (Vol. v., p. 152.).--MR. CHADWICK inquires the meaning of this
word. In Bosworth's _Anglo-Saxon Dictionary_ I find, "_Hyrne_, a horn,
corner;" "_Hirne_, an angle, a corner;" and in Halliwell's _Dictionary
of Archaic and Provincial Words_ I find "_Hirne_, a corner." In many
villages in the fen districts of Lincolnshire are found places called
the _Hirne_, the _Hurne_, or the _Horn's-end_ all being portions of the
respective villages situated in an angle or corner at the extreme end of
the parish.
"Horncastle in Lincolnshire, the Banovallum of the Roman
geographer Ravennas, derives its name from its situation in an
angle formed by the junction of two small rivers, the Bane and the
Waring. Horncastle is a corruption of _Hyrncastre_, a
fortification in an angle or corner."
See Weir's _Horncastle_.
