EFFICIENT and EFFECTIVE

QUESTION: What's the difference between EFFECTIVE and EFFICIENT?

ANSWER:

These two qualitative adjectives are often confused. If somebody or something is EFFICIENT, then he, she or it works in a well-organised way, without wasting time or energy.
Consider the following examples:
- She was efficient in everything she did and was frequently commended for exemplary service to the organisation.
- He has not made very efficient use of his time in revising for these exams: he has made no notes and his concentration spans appear to last for no longer than ten minutes.
- This engine is really efficient, it can run for 30 km on only 1 litre of fuel.

If something is EFFECTIVE, it works well and produces the results that were intended.
Consider the following examples:
- These tablets really are effective. My headache is much better now.
- The only effective way to avoid hay fever at this time of the year, if you are a sufferer, is to stay indoors.
