Creating New English Words

English is probably the only language that creates words and than often discards them just as quickly. A great example of this is the word "homicide bomber". It was created just after 9/11 and quickly lost traction. "Homicide Bomber" was created and disseminated by the US government to replace the word "suicide bomber", because it better explained the true nature of that act. Whether they were correct in their assertion or not is of course a matter of opinion. Nevertheless, it does provide an interesting case study for English Language Learners into a variety of topics, such as: the construction; changing meaning, and usage of words.
