Words by myself is a vocabulary builder. It will display a word, and you have to determine if it is a word, or a made up word. This is all in English language with words up to 15 characters long.
The dictionary is robust with a number of prefixes and suffixes on words.
Answering a question correctly gives you the definition of the word if it is in fact a word.
During the first run it may take a few seconds to setup the database, please be patient.
