Answer 1

It looks like you have two separate things going on. One of is the autocomplete and the other some kind of word/phrase definition?

typeahead.js is only going to address the first part but it seems easy enough. Adapting the example from the github page, you'd want something like:

$('input.englishwords').typeahead({
  name: 'words',
  local: ['application', 'best', 'best wishes']
});

EDIT:

You'll have to parse your JSON object into an array or into an object that typeahead wants. Something like:

var typeList = [];

for (var i = 0; i < Words.length; i++) {
    typeList.push(Words[i].EnglishWords);
}

then:

$('input.englishwords').typeahead({
  name: 'words',
  local: typeList
});
