What are the only 4 words in the English language that end in "dous"?
well i think that you must all go through the statement n the given problem which says: 4 words in "THE ENGLISH LANGUAGE" in which you lay stress on the letters in caps. in these you can make words which might end in dous. I hope you all understand what I actually mean to say. Just go trough all possible words that can be formed from the letters of "The English Language". Only then you can get "ONLY 4 WORDS" or else as Charlie has mentioned there exists more than 4 in english language and not in "THE ENGLISH LANGUAGE". Think about it agin all of you.
