_A Tye_ (Vol. iii., p. 263.) is described by your correspondent as a
place where three roads meet. Perhaps he means a place where one road
divides into _two_. The nucleus of old English towns will be almost
always found to consist of such a fork of one road into two, requiring
three principal gates or entrances, and distinguishing the plans of
towns from those of cities, in which four roads meet, forming the
Carfoix, and requiring four principal gates. Is there any affinity of
the words _two_, _tye_, and _town_? The parallel case of the junction of
two rivers into one affects the names of places situated there, as
_Tiverton_.
