Difference Between Effective and Ineffective

Effective vs Ineffective

The differences between “effective” and “ineffective” is that one word is the opposite of the other.

In the English language, the word “effective” is used as an adjective and a noun. It means:

Something which is capable of producing the expected or intended results. For example, “Effective talks between two countries to maintain peace.”
Something or some action which is sufficient to achieve a purpose. For example, “The effective teaching methods showed immediate results.”
Something or some action which is functional which is in operation at the time. For example, “It was decided that the curfew will be effective at sundown.”
Something producing or leaving a vivid and deep impression. Something which is striking. For example, “an effective painting, an effective photograph, and effective action.”
Fully prepared and accessible for service. For example, The U.S. has effective defense services.”


Someone from the defense service ready for active duty. For example, “Col. Jones is effective on duty.”

Effective is used with many actions, such as: effective communication, effective teacher, effective leadership, effective group, effective products, and effective public speaking. For the success of each action, the methods change. The requirements are not similar for effective leadership and effective products hence it has diverse use.

“Ineffective” is used as an adjective. It is the opposite of the word “effective.” It means:

Something or some action which is not effective which does not produce the intended results. For example, “The talks between the two countries proved ineffective to maintain peace between them.”
Insufficient to produce a certain result. For example, “The medicines she was taking were ineffective.”
Something which lacks artistic impression. It could be writings, paintings, and photographs. For example, “The ineffective photographs of the contemporary sculpture failed to express the motives of the artist.”
Inefficient or incompetent person or action. For example, “The ineffective leadership resulted in the downfall of the political party.”

“Ineffective” is also used with many words, and it changes the whole dynamics of that activity. For example, ineffective leadership, ineffective communication, ineffective teaching methods, ineffective team. All these words are not just words. They imply a bigger meaning.
