Won, now own.
A “word” is an entry on dictionary.com.
A “sentence” is any text that is grammatically correct, has a complete meaning in the English language, starts with a capital letter and ends with a dot.
Repeated words are not allowed.
You are allowed to use punctuation, such as colons and quotation marks, as long as it’s not for making lists (i.e. cheating).
Sentences are rated by word count, however proper names count each as only one word since they can trivially be extended from simple proper nouns by appending surnames.
Common words cannot be changed to proper nouns, although these are allowed as long as they appear as such on dictionary.com.
Finally, as suggested, sentences and text inside quotes must actually make sense, not just gibberish.
That’s it! Good luck, puzzlers!
