Quality (noun) describes how good or bad something is, or a particular characteristic that something or someone has. As an adjective, it means of a high standard. Example: The quality of her written work improved dramatically after six weeks of targeted practice.
What Does Quality Mean?
Quality comes from the Latin qualitas, meaning "nature" or "kind", coined by the Roman orator Cicero as a translation of the Greek poiotēs. It entered English in the 14th century via Old French qualité. The Latin root qualis ("of what kind") is also the source of qualify, qualification, and the prefix quali- in academic terms such as qualitative.
In everyday English, quality is used in three overlapping ways. First, as an uncountable noun describing standard or grade: the quality of the food. Second, as a countable noun referring to a specific characteristic: patience is a valuable quality. Third, as an adjective before another noun to mean "high-standard": quality ingredients, quality time. All three uses are standard in British English.
A key point for ESL learners is that quality by itself is neutral — it can be modified by high, good, poor, or low to specify the level. Saying only "the quality" without a modifier leaves the meaning open. Understanding these nuances will help you use the word with precision in writing and speaking. See Cambridge Dictionary's full entry on “quality” for more examples.

Usage Notes
Using quality correctly
When quality means "standard", it is uncountable: the quality of the work (not "the qualities of the work"). Use the plural qualities only when referring to specific traits or characteristics: She has many admirable qualities.
As an adjective, quality is informal and more common in spoken or commercial English: quality produce, a quality service. In academic writing, prefer phrases such as "high-quality research" (with a hyphen before the noun) or "research of high quality".
Do not confuse quality with quantity. They share the same Latin root (qualis vs quantus) but have completely different meanings: quality = how good; quantity = how much.
Common Mistakes
Watch Out For

Frequently Asked Questions about “quality”
What does quality mean in English?
Quality has two main meanings. As a noun, it describes how good or bad something is ('the quality of the food was excellent') or a particular characteristic that something or someone has ('patience is a valuable quality in a teacher'). As an adjective, it means 'of a high standard': 'a quality product'. Context makes it clear which sense is intended.
Is quality a noun or an adjective?
Quality is primarily a noun, but it is also widely used as an adjective in British English. As an adjective, it comes before a noun and means high-standard: 'quality ingredients', 'quality time', 'quality journalism'. This adjective use is informal in tone and very common in advertising and everyday speech.
What is the difference between quality and quantity?
Quality refers to how good something is, while quantity refers to how much of something there is. They are often contrasted: 'It is better to focus on quality rather than quantity.' Confusing these two words is a very common ESL error because they look and sound similar.
How do you pronounce quality?
Quality is pronounced /ˈkwɒl.ɪ.ti/ in British English. The stress falls on the first syllable: QUAL-i-ty. Note the short 'o' sound in British English (/ˈkwɒl-/) compared to American English (/ˈkwɑːl-/).
What are common collocations with quality?
Common collocations include: high quality, low quality, poor quality, top quality, quality control, quality of life, quality time, air quality, water quality, and ensure quality. These fixed phrases are essential for natural-sounding English, especially in professional and academic writing.

The plural is qualities. It is used when referring to specific characteristics or features: 'She has many admirable qualities.' When quality means the standard of something, it is usually uncountable and has no plural: 'The quality of teaching has improved.'
What is the difference between quality and standard?
Quality describes how good something is in a general, often subjective sense: 'The quality of the performance was outstanding.' Standard is more often used to describe a fixed level of excellence that must be met: 'The work did not meet the required standard.' They overlap in meaning but standard implies a set benchmark, while quality is broader.
Can quality be used as an adverb?
No. There is no adverb form of quality. The adjective form 'quality' is used before nouns ('quality work'), but there is no word 'qualityly'. To express the idea adverbially, use phrases such as 'to a high standard' or use the adverb 'well': 'The work was done well.'

Quality comes from the Latin word 'qualitas', meaning 'nature' or 'property', coined by Cicero as a translation of the Greek 'poiotēs'.
