|Orkney and Shetland|
The name 'Twatt' is, like most of the place-names of Orkney, from the Old Norse language; from þveit meaning 'small parcel of land'. The same Norse word commonly produces the place-name element 'Thwaite' in Yorkshire and the Midlands where the Norse and Danes settled heavily.
This name featured at number four in a list of the most vulgar-sounding names in Rude Britain, along with its Shetland counterpart.
