Comparing EfficientEffective, and Proficient

These three words cover some overlapping territory.

 

Efficient most often describes

what is capable of producing desired results

without wasting materials, time, or energy

While the word can be applied to both people and things

it is far more commonly applied to things,

such as machines, systems, processes, and organizations. 

 

The focus of the word is on how little is wasted or lost 

while the desired results are produced.

 

Effective typically describes things

such as policies, treatments, arguments, and techniques

that do what they are intended to do. 

 

People can also be described as effective 

when they accomplish what they set out to accomplish

but the word is far more often applied to things.

 

Proficient typically describes people, 

and it often is followed by the preposition at

If you are proficient at something, you are very good at it

 

You are, in fact, so good at doing it 

that you are unusually efficient when you do it

One can also be proficient in something, such as a language.
