see:boy forgottenly left....Forgottenly? It isn't acceptable yet, but surely the world of lexicography should open its doors and let the adverb in. Granted, it does not fall trippingly on the tongue, but it precisely identifies a failing that differs significantly from "accidentally" or "mistakenly." True, Webster's defines "accidental" as something that happens "without intent or through carelessness and often with unfortunate results," but there's a distinction. Last month we read of a motorist in Florida who filled his gas tank and drove away with the hose still attached. He did this accidentally, yes, but more precisely he did this forgottenly. It is something to remember.
I wasn't sure which catagory this section belonged in, but it didn't have a good "emerging words" section so......
