Amazing Amazon

Not even in my wildest dreams i assumed that the meaning of "Amazon"(also the name of a e-shopping website) is "female warrior" or "Ambrosia"(a famous fast food outlet) is "Food of the Gods" or to "Annex" is to "attach" or poles "asunder" is poles "apart" or "Perfunctory" is "done without care"(I assumed it to be a science lab or so ..:)).Its funny what a word "sounds like" and what it actually means....At times its incredible to study a language "profoundly"!!!
