distal

Etymology

It is formed from English distant + -al, from the stem dist- of the adjective, on the model of dorsal, ventral and central.^{[2][3][4][5][6]} Hoad calls the formation irregular,^[7] and Klein derives it from Latin distō (“to stand apart”), the source of distant.^[8] Etymonline allows that it may be formed from distance instead.^[3]
