A precise definition says what kind of thing a concept is and what separates it from similar concepts. A good example then shows the concept in use.
This lesson is part of SPM subjects and learning resources. It teaches you how to build a definition, while the concepts and their wording come from your syllabus, textbook and teacher.
What does a good definition contain?
It has two parts: a category and a distinguishing feature. The category puts the concept in a group, and the feature shows why it is not another member of that group.
Take a school “prefect”. The category is a student with a role. The feature is that the role carries duties on behalf of the whole school. Without the feature, “a student with a role” could describe a class monitor too.
The category, feature, example pattern
Write every definition in three short steps.
- Category. “X is a …” naming the kind of thing it is.
- Distinguishing feature. “…, which …” stating what sets it apart.
- Example. “For example, …” giving a case that has the feature.
Keep the whole definition to two or three sentences. Then read your example and ask whether it could also fit a neighbouring concept. If it could, change it.
Worked example: an original concept pair
This practice pair is original and not from any set text. Suppose a syllabus teaches “a pledge” and “an intention” as separate ideas, and a question asks you to define “a pledge” with an example.
| Attempt | Text | Verdict |
|---|---|---|
| Vague | “A pledge is a promise about something.” | No distinguishing feature |
| Memorised | (a full textbook line with nothing adapted) | Correct only if the question matches its wording |
| Precise | “A pledge is a commitment made to another party, which binds the person to act as promised. For example, a person who promises a neighbour to return a borrowed ladder on Sunday.” | Category, feature, fitting example |
The precise version names the category, which is a commitment. It states the feature: it is made to another party and it binds. The example has both: a neighbour, and a binding promise.
The mistake to watch for
A frequent slip is an example that fits the wrong concept. Suppose the student writes, for a pledge, “a person decides in their heart to be kind tomorrow”. That example has no other party, so it belongs to intention, and it shows that the student has mixed the two up.
Check your example against the feature. If the definition says “made to another party”, the example must involve one.
Adapting a definition to the question
Questions word the same request in different ways, such as “define”, “explain the meaning of” or “state what is meant by”. Keep the core of your definition the same and change only the opening to match.
The structured answer self-review tool helps you check a definition for a category, a feature and an example. It works on your own device.
Check yourself
Using the same original pair, write a definition of “an intention” with an example, making sure the example cannot be mistaken for a pledge.
Answer
A sample answer: An intention is an inner decision to act, which is held in the mind and need not be told to anyone. For example, a student decides privately to revise the next day’s chapter before breakfast.
The distinguishing feature is that it is an inner decision with no other party. The example involves no promise to anyone, so it cannot be a pledge.
If your example mentions telling someone, check whether it has drifted towards a pledge.
What to study next
A definition becomes a full answer when evidence supports it in a clear order. Continue with structuring a supported written explanation from reviewed evidence.
If you want a teacher to test your definitions and examples on the concepts in your syllabus, see online one-to-one Usul al-Din tuition. The one-hour trial class (from RM50) is a real lesson, and you can bring the concepts you find hardest.
