Articles: a, an, the and the zero article
A practical decision procedure for a, an, the and no article, including the generic plural rule that costs candidates the most marks.

Article errors are the highest-frequency grammar error in IELTS Writing, and they are visible in almost every sentence, so they weigh heavily on the accuracy half of Grammatical Range and Accuracy. The good news is that four questions resolve nearly every case.
The four-question procedure
Ask these in order for every noun you write.
- Is the noun countable and singular? If yes, it must have an article or another determiner. 'Government should act' is wrong; 'The government should act' or 'A government should act' is right.
- Is it the second mention, or is it made specific by the context or a following phrase? Use 'the'. 'The rise in unemployment', 'the effects of pollution'.
- Is it a first mention of one non-specific countable thing? Use 'a' or 'an', chosen by the sound that follows: a university, an hour, an MBA.
- Is it a plural or an uncountable noun used in a general sense? Use no article. 'Children learn languages quickly.' 'Pollution damages health.'
Where 'the' is fixed
Some uses are not negotiable and are worth memorising as chunks.
- Superlatives: the highest figure, the most significant change.
- Ordinals and unique reference: the first category, the same trend, the only exception.
- Noun + of phrase: the number of students, the proportion of women, the cost of housing.
- Groups referred to as a whole: the elderly, the unemployed, the wealthy.
- Rivers, seas, mountain ranges and plural country names: the Nile, the Alps, the Netherlands.
Where no article is correct
The zero article is a real choice, not an omission. Using 'the' here is just as wrong as dropping it elsewhere.
- Abstract and uncountable nouns in general statements: education, technology, crime, research, information, advice.
- Plural nouns in general statements: 'Cars cause congestion', not 'The cars cause congestion'.
- Most countries, cities and languages: Japan, Toronto, Arabic.
- Institutions used for their purpose: go to school, in hospital, at university.
Corrected examples
Incorrect: The children in developed countries have access to the technology.
Correct: Children in developed countries have access to technology.
Both nouns are general here, so both take the zero article.
Incorrect: Number of visitors increased between 2001 and 2009.
Correct: The number of visitors increased between 2001 and 2009.
'The number of' is a fixed phrase and always takes 'the'.
Incorrect: She is university student studying an engineering.
Correct: She is a university student studying engineering.
Singular countable noun needs 'a'; the uncountable subject name takes no article.
Quick checklist
- Every singular countable noun needs a determiner.
- Second mention or specific reference takes 'the'.
- General plurals and uncountables take no article.
- 'The number of', 'the proportion of', 'the majority of' are fixed with 'the'.
