Etymology
Origin of aid1
First recorded in 1425–75; late Middle English noun aide, eide, from Anglo-French, Old French aide, derivative of verb aid(i)er, from Latin adjūtāre “to help”; see also adjuvant ( def. )
Origin of AID2
A(gency for) I(nternational) D(evelopment)
Explanation
Aid is what you do when you help someone — you come to their aid. Rich countries provide economic aid to poor countries, and if you cut your hand, you'll be looking in the first aid kit for a Band-Aid. You can also use aid as a verb: "The librarian will aid you in your search." English has some words with meanings related to aid, but they're spelled with an -e on the end, because they come from the French. A nurse's aide is someone who assists a nurse. An aide-de-camp is a close assistant and confidant to a military officer, a word often shortened to just aide, to refer to an assistant to a political official.
