Why do we spell Doubt with a b in English I remember being curious about this when I was a child.

But, according to the TED video below, theres a good explanation for this spelling that actually made me appreciate the unusual way English words are sometimes spelled.  Watch the video below, then see if you can answer the listening questions below it.Write your answers in comments and well respond.Most folks cant ____ ___ what its doing there.Why would anyone in their _____ ___ reinsert a silent letter into a spelling?What does the expression above mean?If we look even deeper, we can see ____ __ ____ ___ __ doubt just revealing that B can be.It ____ ___ that if we ____ __ their history, we can see that they both derive from the same Latin forms.What does it mean when we second guess ourselves?What does it mean when we are of two minds?D o you think that this justifies the spelling of Doubt?Ok thanks!
