Determiners and articles
قاعده
Determiners and articles calibrate specificity, distribution, duality, and generic classification across singular, plural, and uncountable nouns.
Determiners define the reference, scope, and quantity of nominal expressions. At B2, mastery involves subtle distributional and generic uses. Distributive determiners each and every both modify singular countable nouns and take singular agreement, but differ in emphasis: each focuses on members of a set individually (Each student presented their own project), whereas every generalizes across all members of a group as a whole (Every room has been inspected). Dual determiners apply strictly to sets of two: both is plural affirmative (Both proposals are viable), either indicates one or the other (You can take either route), and neither negates both alternatives affirmatively (Neither solution is satisfactory). In generic statements, three distinct structures represent an entire class: (1) Zero article with plural count nouns or uncountable nouns (Whales are mammals; Water is essential), (2) The definite article with a singular count noun in scientific, botanical, or formal contexts (The smartphone has transformed modern commerce), and (3) The indefinite article to represent an arbitrary representative of a category (A nurse must remain patient under stress).
به یاد داشته باش
- Apply distributive determiners: each treats individuals separately; every considers the whole collective group; both require singular verbs.
- Distinguish dual determiners: either offers a choice between two; neither negates both options and requires an affirmative verb.
- Deploy generic reference using the definite article with singular countable nouns to designate a representative class or scientific type.

How to read this B2 topic
At B2, the form often changes the focus: agent, emphasis, register, implication, or stance.
1. Decide what is foregrounded
Passive, cleft, inversion, and participle clauses all move attention.
What matters is the evidence.
2. Check register
Some options are grammatical but too informal, too heavy, or unnatural.
Not only did she win, but she broke the record.
3. Watch compressed clauses
Advanced English often removes repeated subjects and auxiliaries.
Having finished, we left.
Articles and quantity
English articles depend on countability, specificity, and whether the listener can identify the noun.
| Meaning | Count singular | Count plural | Uncountable |
|---|---|---|---|
| first mention | a book | some books | some water |
| known / specific | the book | the books | the water |
| general | a tiger / the tiger | tigers | water |
| negative quantity | no book / not a book | no books / not any books | no water / not any water |

استثناها
While neither strictly takes a singular verb in formal writing (Neither of the candidates has accepted), in informal spoken English, plural agreement is frequent (Neither of them have arrived). In competitive exams and formal academic registers, singular agreement remains required.
خطاهای رایج
Using neither with a negative verb (Neither of them couldn't attend - correct is Neither of them could attend), or using every to refer to a group of only two (Every of my parents - correct is Both of my parents). Another frequent mistake is omitting the definite article when making generic scientific statements (Cheetah is fastest land mammal instead of The cheetah is the fastest land mammal).
