We'll
definitely be able to get a table at that restaurant,
it's really off the beaten track.
Esta expresión,
que también se presenta como off the beaten path,
hace referencia a una ruta que es muy golpeada por
muchos pies, es decir, muy transitada.
Beaten track
se registró por vez primera en 1638, con el significado
de la manera normal de hacer algo. Fue Henry David
Thoreau, en el siglo XIX quien la utilizó de manera
figurativa: “It is remarkable how easily and
insensibly we fall into a particular route, and make
a beaten track for ourselves.”
The origin of the phrase is unclear. It might have
originated in the early 1700s in other forms, but
was not very popular. It gained popularity in the
mid 1900s, after a stage show called "Out On The
Town" was performed in 1944 and a film by the same
name came out in 1949.
