JavaScript - Verb Dictionary...

I am writing a script which deals with reading text and extracting information from it. What I want this script to accomplish is outlined below:

1.) The user uploads a .txt file containing an article in a newspaper or a expert from a book etc.

2.) The text is then printed onto the page

3.) After a button is clicked, all the verbs in the article are highlighted
(This doesn't have to be very precise, and will involve the script reading from a verb dictionary/list and highlighting any matches if finds.)

4.) The total amount of verbs is printed at the bottom.

The issues I am having is planning a way to set up this verb dictionary. I was thinking of using an array but would like to avoid it if at all possible as I am dealing with strings not numbers, and I do not want to go into creating a database if it can be avoided.

Does anyone have suggestions on how I can go about setting up some kind of verb list that the script can read from? (On a side note, if there is another language that may be better suited for this kind of program, I have experience in Java and C but would prefer to use JavaScript.) Thanks.
