Another theory is that the derivation of 'narrow' is the more likely connection to angling (as in fishing), which itself stems from a Proto-Indo-European (PIE) root meaning bend, angle.Mugglestone, Lynda (ed.) 2006. The Oxford History of English. Oxford: University Press. The semantic link is the fishing hook, which is curved or bent at an angle.Hogg, Richard M. and David Denison (ed.) 2006. A history of the English language. Cambridge: University Press. In any case, the Angles may have been called such because they were a fishing people or were originally descended from such, and therefore England would mean 'land of the fishermen', and English would be 'the fishermen's language'.Baugh, Albert C. and Thomas Cable 1993 A history of the English language. 4th edition.
