adequacy
Adequacy is when something is good enough for what you need it to do.
Explanation at your level:
Adequacy means having enough. If you have 5 apples and you need 5, that is adequacy. It is a big word, but it just means 'enough.' You can say, 'The food is enough' instead of 'The food has adequacy.' Use this word when you want to sound very formal.
When something is adequate, it is good enough. Adequacy is the noun form. If a chair is strong enough to sit on, we talk about the adequacy of the chair. It is a useful word for school or work when you need to check if things are correct.
You use adequacy to describe if something meets a requirement. For example, 'The adequacy of the evidence' means the evidence is strong enough to prove a point. It is common in reports and formal discussions. It is more formal than saying 'good enough.'
In B2 English, you use adequacy to discuss standards. It is often paired with 'of' (e.g., 'the adequacy of the response'). It implies a critical look at whether a solution or resource truly solves a problem. It is a key term in professional writing and academic essays.
At the C1 level, adequacy is used to nuance arguments. You might question the adequacy of a policy or a legal framework. It suggests a gap between what is provided and what is required. It is an essential term for professional, legal, and academic discourse where precision regarding standards is required.
Mastering adequacy involves understanding its role in formal critique. It is often used in abstract contexts, such as the adequacy of a theory or an explanation. It carries a sense of objective assessment. Its etymological root in 'equality' reminds us that it is about reaching a specific threshold of necessity. In high-level writing, it helps avoid repetitive use of 'sufficiency' or 'satisfaction.'

Hey there! Think of adequacy as the 'Goldilocks' word of the English language. It’s not about being perfect or excellent; it’s simply about being just right for the job.
When we talk about the adequacy of something, we are asking: 'Does this meet the requirements?' If you have a water bottle that holds enough water to get you through a hike, its capacity has adequacy. It isn't necessarily the largest or the fanciest, but it gets the job done.
You will often hear this word in formal or professional settings. For example, a teacher might check the adequacy of a student's research to see if they have enough information to write a good essay. It’s a very practical word that focuses on function over flair.
The word adequacy has deep roots in Latin. It comes from the Latin word adaequare, which means 'to make equal to.'
If you break that down, ad- means 'to' and aequus means 'equal.' So, historically, to have adequacy meant you had brought something up to the level of equality with a standard. Over time, it evolved into the English word we use today to describe anything that is 'sufficient' or 'equal to the task.'
It entered the English language in the 17th century, likely borrowed from the French adéquation. It’s a classic example of how Latin roots help us understand modern English concepts of measurement and value.
Adequacy is a formal noun. You usually won't hear it in casual conversation like, 'Hey, is this pizza adequacy?'—that would sound quite strange!
Instead, you use it when discussing standards, resources, or performance. Common collocations include 'the adequacy of' followed by a noun, like 'the adequacy of the evidence' or 'the adequacy of the funding.'
It is often used in negative contexts too, such as 'doubts about the adequacy of the plan.' This implies that someone is worried the plan might not be good enough to succeed.
While adequacy itself isn't an idiom, it is closely linked to phrases that mean the same thing:
- Up to scratch: Meaning something is good enough.
- Make the cut: To meet the required standard.
- Up to the mark: Meeting the expected level of quality.
- Pass muster: To be accepted as satisfactory.
- Good enough for government work: A humorous (and slightly cynical) way to say something is just barely adequate.
Adequacy is an uncountable noun, meaning you generally don't say 'an adequacy' or 'adequacies.' You talk about 'the adequacy' of a situation.
Pronunciation (IPA): /ˈæd.ə.kwə.si/ in both US and UK English. The stress is on the first syllable: AD-e-qua-cy.
It rhymes with words like legacy or fallacy. Remember to keep the 'kw' sound clear in the middle—it’s not 'a-de-ka-sy,' but 'a-de-kwa-sy.'
Fun Fact
It comes from the same root as 'equal'.
