title: NLTK single-word part-of-speech tagging
body: <p>Is there a way to use NLTK to get a set of possible parts of speech of a single string of letters, taking into account that different words might have homonyms?</p>
  
  <p>For example: report -> {Noun, Verb}  ,  kind -> {Adjective, Noun}</p>
  
  <p>I have not been able to find a POS-tokenizer that tags part-of-speech for words outside of the context of a full sentence. This seems like a very basic request of NLTK, so I'm confused as to why I've had so much trouble finding it.</p>
