Tuberculous is an infectious disease.
Infectious diseases can rapidly spread in underdeveloped societies. He did not go to work that day because his coughing might have been infectious.
The tumor was tested and the doctor said it was malignant. That is a great sentence to use since the word means infectious disease.
how would you use the word demacracy in a sentence?
Since that is not a word I would not attempt to use it in a sentence.
You just did use the word colonize in a sentence.
i do not know how to use the word turbulent in a sentence
no such word as "reasonableness' you would have to use " reasonable conduct" in your sentence.
how would you use the word finished in a command sentence
The word mores is not a word.
1. you did just use that word in a sentence 2. if a doctor would use the word tumor in a sentence they would probably say "we need to remove the tumor from this persons body."
Yes, of course. A word you couldn't use in a sentence would be a pretty poor excuse for a word.
