That depends on what essay you are planning to write. (Argumentative, Persuasive, etc.) However, I can tell you the basic elements that essays are constructed in order for you to get a gist of it.
The first thing that all essays have in common is the introduction paragraph. Here, you should introduce what you are going to talk about, and present your stance.
The second thing that all essays have in common is the body paragraphs. Now, the number of body paragraphs really depends, but in the body paragraphs, you should talk about your stance in more detail, and possibly provide evidence and reasoning as to why you think that certain way.
The final thing that all essays have in common is the conclusion paragraph. This is pretty self-explanatory, but here, you wrap up your essay by clarifying your points one last time and possibly giving a call to action.
I hope this helped you, I wish you the best of luck when writing future essays!
