Jakob Jakobsen, An Etymological Dictionary of the Norn Language in Shetland…
“ Words with Old Northern meaning changed in form into Eng. (L.Sc.) by divers influences. When a Norn word, cognate with an English word and having the same sense, has been superseded by the Eng. (L.Sc.) form, a similar anglicising sometimes takes place in a Norn word of the same form as the other, but of different meaning. ”
