title: Jquery/Javascript check my word is valid or not.
body: <p>I am designing an simple application, which plays with words. 
  every time a user types a word, i need to validate the word that it is proper English word or not. 
  my requirement is simple like if i pass a word to a method, it just have to return me true(Valid) or false (invalid)</p>
  
  <p>Can i find any J Query API or even if i get a list of English words as a 
  JS-file. I can use it in my application. </p>
