All essays need a clear beginning, and end.

I suppose the right word would be middle.

Explanation:

Most well-written essays have three basic parts:

1. an introduction

2. a body

3. and a conclusion.

Your introduction an and conclusion should be clear as well as draw the reader in and leave the reader without abruptly cutting off the essay short. The body forms the details of the essay itself and is a component that cannot be overlooked.

I hope this is helpful!
