The latter name is discussed by Marstrander (112–14) and derived by him from ON flesiu -vík . The second element is ON vík, 'bay,' a word of which there seems to be no other example on the Cumbrian coast.

This sense would be appropriate to the situation of Fleswick, which is a bay among the sharply stratified rocks of St Bees Head.
