I need a good scheme for choosing a keyword from a definition. The scheme must be universal because I'm reading from a list of 5000 words with definitions. This is for my hangman game I made, and I want to give the user a clue as to what the word is. At the end, wether they win or lose, I show them the definition. I've tried grabing the largest word in the definition and puting that as the clue, but sometimes the largest word means the direct opposite of what the word actually is.
Here is a few definitions in the list if that helps:
able-bodied adj. Competent for physical service.
ablution n. A washing or cleansing, especially of the body.
abnegate v. To renounce (a right or privilege).
abnormal adj. Not conformed to the ordinary rule or standard.
Any suggestions is greatly appreciated.
