Etymology

Origin of allow

First recorded in 1250–1300; Middle English alowen, from Anglo-French al(l)o(u)er “to place, allot, allow,” Old French aloer “to place,” from Late Latin allocāre; al-, locus; the older sense “approve, sanction” and Middle English sense “praise” probably by taking the Anglo-French verb as representing Medieval Latin, Latin adlaudāre “to praise”; ad-, laud

Explanation

If you allow your best friend to read your diary, it means you've given him permission to do it. The verb allow means to let someone do something. You can allow casually, like when you allow your friend to bite off a few pieces from your candy necklace, or more officially, as when a city government decides to allow dogs to be brought into restaurants. Allow can also be used to mean "admit the truth of," so you could say, "Fine, I'll allow that dogs aren't any dirtier than many people, but it's still strange seeing them in restaurants."
