What are the only 4 words in the English language that end in "dous"?
(In reply to
re(3): MY IDEA !!!! JUST THINK !!!! by Bryan)
I agree to what you are saying Bryan but then why don't you think a bit more on this. When you have seen that not a single prefix from Charlie's list of words can be made from the letters in THE ENGLISH LANGUAGE, then at the same time, there does not exist "EXACTLY (ONLY) FOUR WORDS IN THE ENGLISH LANGUAGE" (as mentioned in the question) that end in "dous". What do you have to say for that ?
