Origin

"Allow" comes from Middle English "allowen," borrowed from Anglo-Norman "allouer," from Medieval Latin "allaudāre," which merged with "alouer" from Medieval Latin "allocō" ("to assign"). It is a doublet of "allaud" and "allocate," and its resemblance to Old English "ālīefan" and German "erlauben" is only coincidental.
