An opinion essay is a formal piece of writing in which you share your thoughts on a specific topic. You should express your opinion clearly and give reasons and examples to support your point of view.
Remember that when we write in formal style, we must not use contractions or informal words or expressions.
Parts of an opinion essay
An opinion essay must have 3 parts:
1. Introduction
In this paragraph you have to introduce the topic. You introduce the topic by restating the question or the title of the essay in your own words. Here you have to say if you agree or not with the question or the title of the essay. You can agree, disagree or partially agree.
2. Body
In this section you have to support your opinion with reasons and examples. You must include at least three reasons. Break it into several paragraphs. Write one paragraph for each supporting reason. Don’t forget to include examples or facts.
3. Conclusion
Summarize your ideas and restate your opinion using different words.
Transition words and phrases
In your essay you have to organize all your ideas in a logical and coherent way. You can use different transition words or phrases to connect your ideas. Transition words and phrases help the reader understand your point of view easily.
