All and All of — English Grammar Exercises
None of the bread is fresh. Most of them agreed. Every student has a book. — master every quantifier pattern.
All and All of in English
'All' is one of the most flexible quantifiers in English, but its structural rules — when 'of' is required, where 'all' sits relative to 'the', and how it differs from 'every' — generate consistent errors at B1–B2 level. Analysis of the International Corpus of Learner English (ICLE) shows that 'all of students', 'the all books', and 'all of them are' (with wrong agreement) are among the twenty most frequent quantifier errors at intermediate level.
General vs Specific: The Core Distinction
All the children in my class passed. (specific group — 'all' + 'the' + noun)
All of the children in my class passed. (= 'all the children' — interchangeable)
All of them passed. ('of' required before pronouns)
Word Order: All Before The
'All' always precedes 'the' — never after it:
✗ I read the all instructions. (wrong — 'all' must come first)
Common Mistakes
✗ I have read the all books on the list. → ✓ I have read all the books on the list.
Frequently Asked Questions
When do you use 'some' and when do you use 'any' in English?
The core rule: use 'some' in positive sentences ('There's some milk in the fridge') and 'any' in negatives and questions ('There isn't any milk', 'Do you have any cash?'). Two key exceptions override this rule. First, use 'some' in offers and requests — 'Would you like some coffee?' and 'Could I have some water?' — because the speaker expects a positive answer. Second, use 'any' in positive sentences to mean 'whichever / it doesn't matter which': 'You can sit in any seat.' 'Any' also follows near-negative words like 'hardly', 'without', and 'rarely': 'We got there without any problems.'
What is the difference between 'all students', 'all the students', and 'all of the students'?
'All students' (no article, no 'of') makes a general statement about students as a group: 'All students need encouragement.' 'All the students' and 'all of the students' both refer to a specific, identified group: 'All the students in my class passed.' The two forms with 'the' are interchangeable, though 'all the' is more common in everyday speech. The same pattern applies to 'most': 'Most people' (general) vs 'most of the people' or 'most of them' (specific). You can never say 'all of students' or 'most of people' — 'of' always needs a determiner after it.
What is the difference between 'no' and 'none'?
'No' is a determiner: it must be followed directly by a noun ('There is no milk', 'She has no idea'). 'None' is a pronoun: it stands alone ('How many tickets are left? — None.') or precedes 'of' + determiner + noun ('None of the tickets are left', 'None of them passed'). The most common error is 'none of students' — you must say 'none of the students'. The second common error is double negation: 'She didn't say nothing' is wrong; choose either 'She said nothing' or 'She didn't say anything'.
Does 'none of' take a singular or plural verb?
When 'none of' is followed by an uncountable noun, use a singular verb: 'None of the water was clean', 'None of the bread is fresh'. When followed by a plural countable noun, both singular and plural verbs are acceptable: 'None of the students was absent' (formal) and 'None of the students were absent' (informal, increasingly standard). The same logic applies to 'all of' and 'most of': the verb agrees with the noun that follows 'of', not with the quantifier itself — so 'All of the information has been updated' (uncountable), but 'All of the guests have arrived' (plural countable).
