Lesson 22
Determiners: Each, Every, Both, Either, Some/Any and Enough
This lesson groups five rules that students commonly confuse because they look similar on the surface. Check countability, number and the exact quantity meaning. Work through the examples slowly once; speed comes after the pattern is clear.
What you will learn
- Understand and apply: 'Each' focuses on members separately; 'every' views all members individually within a group.
- Understand and apply: 'Both' takes a plural noun and plural verb.
- Understand and apply: 'Either/neither of' is traditionally singular in formal agreement.
- Understand and apply: 'Some' and 'any' depend on sentence meaning, not only polarity.
- Understand and apply: 'Enough' comes before nouns but after adjectives/adverbs.
For every rule: spot the trigger → identify the grammatical relationship → apply the form → check meaning.
Before you start
Try the warm-up without checking the rule. The purpose is to expose the instinct you currently use, not to score marks.
Which sentence follows the target grammar pattern?
A. Each student received feedback, and every section was reviewed.
B. Every of the students received feedback.
Answer: A. Each can be used for two or more and can stand alone; every is followed by a singular count noun and normally refers to three or more as a complete set.
Rule 1 · G106
'Each' focuses on members separately; 'every' views all members individually within a group
Each can be used for two or more and can stand alone; every is followed by a singular count noun and normally refers to three or more as a complete set.
Correct example
Each student received feedback, and every section was reviewed.
Incorrect example
Every of the students received feedback.
Interpretation
Each can be used for two or more and can stand alone; every is followed by a singular count noun and normally refers to three or more as a complete set. In a test, do not memorise this as an isolated sentence. Check countability, number and the exact quantity meaning. The correct example shows the pattern in context; compare it directly with the incorrect version and identify the exact word that must change.
Why it matters
Quantifiers and determiners encode precise differences in number, countability and emphasis.
Common exam trap
Ignoring whether the noun is countable and whether the intended quantity is positive, negative or approximate.
How to spot it
Label the noun countable/uncountable and singular/plural before selecting the determiner.
3-step solving method
- Check countability and number.
- Identify the intended quantity/attitude.
- Select the compatible determiner.
Why the incorrect example fails
The target structure requires this rule: Each can be used for two or more and can stand alone; every is followed by a singular count noun and normally refers to three or more as a complete set. In the incorrect version, the repair is to replace “Every of the students” with “Each student”; replace “feedback.” with “feedback, and every section was reviewed.”. That is the exact edit a student should be able to justify in an error-spotting question.
Nuance and memory hook
Each can also stand alone ('Each was checked'); every normally needs a following noun or 'one'.
EACH = one at a time.
Quick check
Without relying on what 'sounds right', explain which part of this sentence violates the rule: “Every of the students received feedback.”

Explain the error rather than guessing by sound
Why is this sentence problematic in the target rule? “Every of the students received feedback.”
Rule 2 · G107
'Both' takes a plural noun and plural verb
Both refers to two members together and is grammatically plural.
Correct example
Both passages are difficult.
Incorrect example
Both passage is difficult.
Interpretation
Both refers to two members together and is grammatically plural. In a test, do not memorise this as an isolated sentence. Check countability, number and the exact quantity meaning. The correct example shows the pattern in context; compare it directly with the incorrect version and identify the exact word that must change.
Why it matters
Quantifiers and determiners encode precise differences in number, countability and emphasis.
Common exam trap
Ignoring whether the noun is countable and whether the intended quantity is positive, negative or approximate.
How to spot it
Box the finite verb, then ask which noun actually controls it. Ignore nearby nouns that belong inside phrases.
3-step solving method
- Check countability and number.
- Identify the intended quantity/attitude.
- Select the compatible determiner.
Why the incorrect example fails
The target structure requires this rule: Both refers to two members together and is grammatically plural. In the incorrect version, the repair is to replace “passage is” with “passages are”. That is the exact edit a student should be able to justify in an error-spotting question.
Nuance and memory hook
Quantifier choice can change the speaker's attitude as well as the literal quantity.

Rule 3 · G108
'Either/neither of' is traditionally singular in formal agreement
Either of and neither of are followed by plural nouns but traditionally take singular verbs in formal English.
Correct example
Either of the routes is acceptable.
Incorrect example
Either of the routes are acceptable in strict formal usage.
Interpretation
Either of and neither of are followed by plural nouns but traditionally take singular verbs in formal English. In a test, do not memorise this as an isolated sentence. Check countability, number and the exact quantity meaning. The correct example shows the pattern in context; compare it directly with the incorrect version and identify the exact word that must change.

Nuance and memory hook
Modern informal English sometimes uses plural agreement, but a formal exam may prefer the traditional singular pattern.

Rule 4 · G109
'Some' and 'any' depend on sentence meaning, not only polarity
Some is common in affirmative statements and offers/requests expecting agreement; any is common in negatives, questions and unrestricted meanings.
Correct example
Would you like some water? I do not have any coffee.
Incorrect example
Would you like any water? I do not have some coffee, in the ordinary meanings intended.
Interpretation
Some is common in affirmative statements and offers/requests expecting agreement; any is common in negatives, questions and unrestricted meanings. In a test, do not memorise this as an isolated sentence. Check countability, number and the exact quantity meaning. The correct example shows the pattern in context; compare it directly with the incorrect version and identify the exact word that must change.

Rule 5 · G110
'Enough' comes before nouns but after adjectives/adverbs
Place enough before a noun and after an adjective or adverb.
Correct example
We have enough time, and the explanation is clear enough.
Incorrect example
We have time enough, and the explanation is enough clear.
Interpretation
Place enough before a noun and after an adjective or adverb. In a test, do not memorise this as an isolated sentence. Check countability, number and the exact quantity meaning.
