Word classification algorithms
This is a standard problem in Natural Language Processing (NLP).

Classifying whether each word is a noun, verb, etc., is known as "part-of-speech tagging".  Searching on that term should turn up a lot of information about how to do that.

If you want to tag the words in some other way, you might be able to use other tagging algorithms.  They generally use some sort of machine learning approach and will probably require a large training set (200 words won't be enough).
