Origin: 1350–1400; Middle English al(
e)
y <
Middle French alee walk, passage, derivative of feminine of
ale, past participle of
aler to walk (
French aller), probably <
Vulgar Latin *allārī, regularized from
allātus, the suppletive past participle of
afferre to bring (passive
afferrī to be moved, conveyed, to betake oneself);
French aller often allegedly <
Latin ambulāre to walk (
see amble), but this offers grave phonetic problems, since the
m and
b would not normally be lost
