Main Idea (Main Idea, Main Thought) and Supporting Idea

Understanding Main Idea and Supporting Idea

Main ideas and supporting ideas are the most crucial elements in a paragraph. This is because these two elements contain the content or message the author wants to convey based on the topic raised. The main ideas and supporting ideas will be compiled by the author with the principle of inter-sentence cohesion so that they become good paragraphs, i.e. one idea will complement or support another idea. In addition, the main idea has other names, including the main idea, main idea, main idea, main idea, etc. Meanwhile, supporting ideas have only one other name, namely explanatory ideas.

Actually, the main idea is what or who (subject) and why or how (predicate) is being discussed, which is located in the main sentence. Therefore, if you want to find the main idea, you must first determine the location of the main sentence. Meanwhile, the explanatory idea of ​​its existence serves to clarify or support the main idea.

In general, the writer will first think about what the main message he wants to convey in an article is. The result of this thought will be the main idea which will be clarified with supporting ideas. For example, the author has the main idea that Indonesia is respected because of the sharpness of its vision and mission, the main sentence might be the sharpness of vision and awareness of the strategic position of the archipelago that has brought this country to be respected by other countries.

Meanwhile, the author will write supporting ideas why Indonesia is respected because of the sharpness of its vision and mission in several explanatory sentences written by taking into account the principle of coherence.

Characteristics of Main Idea and Supporting Idea

As explained above, the main idea can be said as the main thing the author wants to convey in a paragraph. Therefore, the first characteristic that can describe the main idea is that it consists of complete sentences that can stand alone (dependent clause). Because it can stand alone, the main idea must not contain reference words (this, that, that, etc.) or conjunctions between sentences (however, therefore, meanwhile, etc.).

In contrast to the main idea, because of its nature which seeks to clarify, the supporting ideas contain reference words and conjunctions between sentences or what are generally referred to as cohesion tools. Furthermore, the characteristics of the main ideas and supporting ideas are as follows.

Main Idea Features
The form of a complete sentence and can stand alone or can cause other sentences.
There should be no reference words and conjunctions between sentences.
Contains the source of the core problem.
If there is a word is, is, is, thus, and so, it is most likely the main idea.
Characteristics of Supporting Ideas
In the form of a sentence that is written because it tries to explain another sentence.
Contains reference words and conjunctions between sentences.
When interpreted, the existence of a sentence is caused by another sentence.

How to Find Main Ideas and Supporting Ideas

The main idea in a paragraph can be found how to read the whole text, and understand well the theme chosen by the author, then choose which sentence is the cause of other sentences and in that sentence is the location of the main idea. After the main idea is found in the main sentence, it is clear that the ideas in other sentences are the main idea. There are two types of main ideas: The main idea is the same as the main sentence and the main idea is different from the main sentence.

Example of the same main idea as the main sentence
SMAN 99 Jakarta is one of the best public high schools in East Jakarta. (2) This Public High School was ranked first as a public school with the highest National Examination (UN) scores in Jakarta. (3) In addition, this SMA has A+ accreditation and is ISO certified. (4) Not only that, this SMA also has the majority of its students each year succeeding in achieving State Universities (PTN).

The main sentence of the general classification section: “SMAN 99 Jakarta is one of the best public high schools in East Jakarta.” The main idea of ​​the main sentence: “SMAN 99 Jakarta is one of the best public high schools in East Jakarta.” Meanwhile, the main ideas include:

Sentence (2): SMAN 99 was the best in the National Examination (UN) ranking.

Sentence (3): SMAN 99 with ISO predicate and A accreditation

Sentence (4): The majority of SMAN 99 students won PTN.

The main idea is not the same as the main sentence. For example,
Apart from the color, there is a difference between brown rice and white rice. (2) White rice still has the entire outer layer, while brown rice has the outer layer removed, but still leaves other parts. (3) In addition, brown rice is more consumed for someone who is on a diet program and is considered healthier because it contains less glucose than white rice.

The main sentence of the general classification section: “Apart from the color, there is a difference between brown rice and white rice.” The main idea of ​​the general classification section: “There is a difference between brown rice and white rice.” Meanwhile, the supporting ideas, among others.

Sentence (2): There is an entire outer layer on white rice, while brown rice has the largest layer removed, but leaves other parts.

Sentence (3): Brown rice is considered healthier for health because it is lower in glucose than white rice.
