inefficiency in [doing something]

inefficiency of [a system]

Usage Note

Most often uncountable in this sense. Subject is typically a system, process, organisation, or working method — not a single person's behaviour in isolation.

Common Mistakes

He has a big inefficiency at work.
He works very inefficiently.
inefficiency describes a condition of a system or method, not a single person's habit; use the adverb 'inefficiently' for individual behaviour.

Antonyms

Grammar Patterns

inefficiencies in [a system]

remove / eliminate / identify inefficiencies

Usage Note

Countable and almost always plural. Distinguish from sense 1: sense 2 names individual fixable items (you can count them and list them), while sense 1 names the overall poor state.

Common Mistakes

There is one inefficiency on my desk.
My desk setup is inefficient.
a single small problem is not normally called 'an inefficiency'; the countable noun is used for clearly identified weaknesses inside a system.

Word family

Synonym discussion

Sense: noun/1

All four words describe things going badly, but they target different causes. Inefficiency points at a system or method that uses too much time, money, or energy to get a result — the focus is on the ratio of input to output. Waste is broader and more neutral about cause: any leftover resource, food, or effort that no one benefits from. Incompetence is the harshest of the group; it puts the blame squarely on a person's lack of skill or judgement, not on the process they work inside. Disorganisation describes things being in a messy or unstructured state, but does not by itself say that resources are being lost. A team can be disorganised yet still cheap to run; an inefficient team uses more resources than it should. Compare: "The hospital suffers from inefficiency" (the system is slow and costly) vs. "The director was sacked for incompetence" (a person could not do the job).

Etymology

LatinOld FrenchEnglish

Formed in English in the early 1600s by adding the negative prefix 'in-' (meaning 'not') to 'efficiency'. Efficiency itself comes from Latin 'efficientia', meaning 'the power of producing a result', from the verb 'efficere' ('to bring about, accomplish'). So inefficiency literally names the lack of that result-producing power: effort goes in, but not enough useful output comes out.
