A tautology is needless repetition of an idea, statement, or word.

So let us look at the name of this place, Torpenhow Hill (illustrated in the photo). The language of the old North of England was closely related to Old Welsh. Cumbria comes from the same root as Cymry, the Welsh word meaning "fellow-countrymen", revealing Cumbria's roots. The hill's name today goes back to those ancient times.

When the Saxons arrived in the area and asked the then Welsh-speaking inhabitants the name of that hill, the answer was “pen” which means "hill" in Welsh. So the Saxons used their word for hill, “tor,” added it the name they were told, and called it Torpen (hill hill).

Later the Norse invaders arrived and the same process added the their world for hill “Haugr”. So now it was Torpen Haugr (Hill Hill Hill).

Later, the English called it Torpenhow Hill (Hill Hill Hill Hill).

A four-language tautology!
