Use of All, most, half and none

Use of All, most, half and none Edit

Mastering the use of all, most, half and none is essential for proper English grammar. Learn how to form generalizations, use specific determiners with "of", and avoid common structural mistakes with these quantifiers.

How to Make Generalizations Using All and Most

We can use all/most + noun to make a generalization.

All rabbits love green food.
Most package systems have two cassette decks.
Most pollution could be avoided.

These are about rabbits, package systems and pollution in general.

Compare these sentences.

Most people want a quiet life. (people = people in general)
Most of the people here are strangers to me. (the people = a specific group of people)

Pro Tip: As well as most, we can also use majority of and more than half. For example: The majority of package systems have two cassette decks. More than half the pollution in the world could, be avoided. The opposite is minority of or less than half. A minority of systems have only one deck.

When to Use All, Most, Half and None With "Of"

When we are talking about something more specific, we use all/most/half/none + of determiner + noun.

All (of) our rabbits died from some disease.
Most of the pubs around here serve food. (NOT the most of the pubs )
Copying takes half (of) the normal playing time.
None of these jackets fit me any more.

We can leave out of after all and half. But when there is a pronoun, we always use of.

We had some rabbits, but all of them died.
I read the book, but I couldn't understand half of it.

Common Mistakes to Avoid: Note the following special rules:

We can use half a/an to express quantity (e.g., We waited half an hour. I could only eat half a slice of toast.).
We can use a number after all (e.g., all fifty systems).
We can use all after an object pronoun (e.g., The rabbits died. We lost them all/all of them.).

Where Can We Place "All" in a Sentence?

It can also come in mid position or after the subject.

The systems can all copy a tape from one deck to the other.
The rabbits all died.
Who went to the disco? ~ We all did.

We cannot use most in this position, but we can use the adverb mostly.

Package systems mostly/usually have two cassette decks.

How to Use "None" and "Not All" Correctly

None has a negative meaning. We use it with the of-pattern.

None of the rabbits survived. They all died.

NOT All ofthe rabbits didn't-survive.

But not all means 'less than all'.

Not all the rabbits died. Some of them survived.

Key Takeaways

Use all/most + noun for general statements.
Use all/most/half/none + of + determiner + noun for specific groups.
Always use of before pronouns (e.g., all of them, half of it).
None carries a negative meaning, whereas not all means "less than all."
