Obviously, you don’t need to write a lot about such words as “ball”, “mug”, or “shoe”.
Definition essays require you to write your personal definition of a certain word.
Even though this task is more about your own understanding of a certain subject, action or idea, your thoughts must be based on good research and supported by evidence. Now you’ll need to expand your definition and develop it by using sources and references.
For instance, the word “pain” may be explained quite differently depending on the context. Both things are familiar to everyone from your audience, and you can think about your own understanding of pain, by recalling moments associated with pain of any kind.
Check a dictionary to find the traditional definition.
With such an approach, even the most obvious thing may be a subject of a great essay. Choose a subject that can be considered in different dimensions and contexts.
This will allow you to provide more information and use more sources.
You need to find a topic which can be considered from various angles and which you have strong associations with.
It may be love, feminism, justice, truth, democracy, family, and so on.
Such concepts can be easily described by using various sources and your own experience.
No matter what associations or feelings you have related to a chosen word.
