I'm having trouble choosing a topic for my essay. I have an idea of what I want to write about. I'm just not quite sure on the topic.
It's an argumentative essay.
For an argumentative essay, you should choose something you strongly believe in. If it's wide open, you should also choose something you know a lot about. For example, you might write about a policy at your school or in your city you want changed.
When choosing a topic it is best to think about your passions! Is it music, art, sports, relationships, or politics? How do you spend your leisure time? What relationships are important to you? Are you religious? What is the purpose of your life? The topic should be thought provoking if you want to write about something interesting. Avoid descriptive, research based topics that are more like reports rather than essays where you are sharing your passions and feelings about a topic. Include the pro and cons and cite examples. Include what made you choose the topic and end with how important your topic is to you and society.
It is difficult to know how to help you with your question because you haven't said what topic you are thinking about.
The best advice I can give you is to take a position that you can support. Your main idea is an argument for or against something in an argumentaive essay. This means that after you state your argument in the introduction, the rest of the essay, until you get to the conclusion, should include points that will support the position you are taking.
What kinds of support do you need? You can support a position with examples, with statistics, with personal knowlege, or with expert opinon. I do not know if you are expected to do research to support your argument, but if you are expected to do so, make sure that you provide the sources that you use to support your position.
You are, of course, welcome to submit another question that gives us some idea what your topic might be.
Good luck to you.
I am somewhat puzzled by your question. If you know what you want to write about, that is your topic. Or is it that you have selected a broad area and now want to narrow down to a topic hat is more specific. If that is the case, you can try the following approach.
Prepare a list of all the related topic that you can think of. Then start eliminating topics from the list using multiple criteria like your interest, availability of information, and how interesting it will be to the readers. This elimination process can be very quick without too much thinking. But when you are left with just two or three topics on your list, you can compare the relative suitability of topics more carefully. Based on this comparison you can make the final choice.
Just remember this, you are the best judge of what topic interests you most, and for which topic you can obtain reasonably good information.
