These two qualitative adjectives are often confused, Kisy. 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 hasn抰 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抯 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.'
