using more resources than needed
Not working in a good or fast way and wasting time, energy, or money.
Mẫu sử dụng:
[something] is inefficient / inefficient [system/method/process/device]
Lỗi thường gặp:
Learners often confuse "inefficient" with "ineffective." "Inefficient" means something works but wastes time or resources. "Ineffective" means it does not really work or does not achieve the goal. For example, a slow computer is inefficient, but a medicine that does not help at all is ineffective.
Từ đồng nghĩa

|

|
ineffective (Stresses not achieving the desired result; sometimes overlaps but does not always imply wasted resources.)
Từ trái nghĩa

not working well or productively
Describing a person who does not work in a good, fast, or organized way and wastes time or effort.
Mẫu sử dụng:
[someone] is inefficient at [task] / an inefficient [worker/employee/manager]
Lỗi thường gặp:
Learners sometimes use "lazy" when they really mean "inefficient." "Lazy" means someone does not want to work. "Inefficient" means they may work, but in a poor or badly organized way. Also, learners sometimes say "he works inefficient" instead of the correct adverb phrase "he works inefficiently."
Từ đồng nghĩa

|

Từ trái nghĩa
efficient (Describes a person who uses their time and energy well and gets a lot done.)
|
