The subject sentence is made up of two parts: the topic itself and a governing notion. The topic of the paragraph is what the paragraph will be about, and the guiding concept explains WHY the paragraph is being written. These two elements are called the controlling ideas of the paragraph.
Now, look at our topic sentence again: "A paragraph should have a topic sentence and supporting details." This means that our paragraph should have one thing to talk about and we should explain why it is important.
In other words, the controlling idea is both topic-related and theme-related. A good topic sentence should be specific and concise while giving clarity on who, what, when, where, and how. It can also be interesting or relevant to the audience.
Here are some examples of good topic sentences: "This article discusses how music has influenced history over time." "This essay explores how television affects society today." "This piece of writing aims to identify what makes for a great leader." "This piece of work questions whether Dickens' popularity will continue into the future."
Poor topic sentences are vague and general. They tell the reader nothing specific about why this paragraph is being written.
"The theme sentence" is the sentence that expresses the primary concept of the paragraph. It is without a doubt the most essential statement in the paragraph. The subject sentence is often made up of two parts: (a) the topic and (b) the governing notion. The topic sentence usually introduces the topic and states it clearly for readers. The governing notion is the idea or concept that gives significance to the topic. It can be stated as the answer to the question, "Why should I care?"
For example, let's say that we want to write about dogs. We could do so by discussing different types of dogs, their behaviors, etc. But that would make the topic sentence too broad; it would not focus on any particular aspect of dogs. Instead, our topic sentence should introduce one specific thing about dogs - they are man's best friend. This tells us what we should be writing about! It also gives us a good idea of how to start writing - by picking an interesting fact about dogs!
Now, this may not seem like much of a topic sentence at first glance, but just think about how many topics there are out there. You can talk about anything under the sun, so this task is quite easy once you get used to it. And don't worry if you can't come up with a topic right away - just start writing about something else and eventually you will run out of things to say.
A subject sentence is the opening sentence of a paragraph that outlines the topic and the paragraph's governing notion. A subject sentence should contain a topic, a governing concept, and the author's point of view. It can be as short as possible while still fulfilling these requirements.
Examples: "The quick brown fox jumps over the lazy dog" and "Photography is an art form that uses light to create images."
Both sentences are subject sentences because they outline their topics ("foxes" and "images") and they express a point of view ("quick" and "photography is an art form that..."). However, the first sentence is more concise than the second one since it does not include any additional information beyond what is contained in the topic itself. Also, notice that both subjects contain multiple ideas (a fox is a furry animal with a tail that jumps over other animals) but only one idea is expressed by each sentence (in this case, the concepts "brown" and "lazy").
It's important to identify subject sentences because they act as hooks for the reader to want to continue reading the paragraph. If there are too many non-subject sentences present, the reader may become confused as to whether or not they should read the rest of the essay.
