* Impulsive: Acting or done without forethought. It suggests a lack of planning or consideration of consequences.
* Representative: Typical of a larger group or category. It suggests something that accurately reflects the characteristics of a whole.
Here's an example:
* Impulsive: A child might impulsively grab a cookie from the jar without asking permission.
* Representative: A survey of 1000 people might be representative of the opinions of the entire population.
While "impulsive" suggests a lack of consideration, "representative" suggests a careful reflection of a larger group. Therefore, they are not opposites, but rather describe different aspects of action and representation.
