Does not matter what topic you will choose, what is really important: really believe that you will find your audience. The topic that you are going to choose needs to be interesting for you personally, in other case it would be really difficult to gather all facts and general information to make a good paper. You need to ask yourself: will my future work be interesting to read? Has my future essay a perspective to become a reason for discussion? Is it possible to be serious in talking about this theme but not so much serious to put to sleep this one, who will read it? If the answers are yes, you have a good chance to write an outstanding definition essay.
"Robert Frost believed sentence tones (which he called 'sound of sense') are 'already there—living in the cave of the mouth.' He considered them 'real cave things: they were before words were' (Thompson 191). To write a 'vital sentence,' he believed, 'we must write with the ear on the speaking voice' (Thompson 159). 'The ear is the only true writer and the only true reader. Eye readers miss the best part. The sentence sound often says more than the words' (Thompson 113). According to Frost:
The function of an argumentative essay is to show that your assertion (opinion, theory, hypothesis) about some phenomenon or phenomena is correct or more truthful than others'. The art of argumentation is not an easy skill to acquire. Many people might think that if one simply has an opinion, one can argue it successfully, and these folks are always surprised when others don't agree with them because their logic seems so correct. Argumentative writing is the act of forming reasons, making inductions, drawing conclusions, and applying them to the case in discussion; the operation of inferring propositions, not known or admitted as true, from facts or principles known, admitted, or proved to be true. It clearly explains the process of your reasoning from the known or assumed to the unknown. Without doing this you do not have an argument, you have only an assertion, an essay that is just your unsubstantiated opinion.
