Difference Between Effective and Efficient

Definition of Effective

Effective refers to the ability to achieve a desired result or goal. If something is effective, it means it produces a strong, decisive outcome or impact. It's about doing the right things to reach an objective.

Definition of Efficient

Efficient, on the other hand, relates to performing in the best possible manner with the least waste of time and effort. It's about doing things in a way that maximizes productivity with minimal wasted resources.

Origin of Effective

The term effective originates from the Latin word “effectivus,” which means “productive, effective.” It has been used in English since the 14th century to denote something that produces a definite or desired effect.

Origin of Efficient

Efficient comes from the Latin word “efficientis,” meaning “producing” or “causing.” It entered the English language in the 14th century, emphasizing the idea of achieving maximum productivity with minimum wasted effort or expense.
