Unit 88: all/all of, most/most of, none/none of etc.

Flashcards covering the grammatical rules for using quantity words with and without 'of' as presented in Unit 88.

General usage of quantity words (all, some, many, etc.)

You use these words directly with a noun to talk about things or people in general, such as 'All cars have wheels' or 'Many people drive too fast.'

Rule for 'some of' or 'most of'

We do not use 'of' when speaking generally; for example, we say 'some people' rather than 'some of people.'

Quantity words with 'of' + the/this/my/etc.

You use 'of' (some of / most of) before specific determiners like 'the', 'this', 'that', 'my', 'these', or 'those' (e.g., 'some of the people', 'most of my time').

Exception for 'all' and 'half'

You do not need to use 'of' after these two specific words; you can say 'All my friends' or 'All of my friends,' and 'Half this money' or 'Half of this money.'

'All flowers' vs. 'All (of) these flowers'

'All flowers' refers to flowers in general, whereas 'All (of) these flowers' refers to a specific group of flowers.

Quantity words with pronouns (it/us/you/them)

You must use 'of' before these pronouns; for example, 'all of us', 'some of it', or 'none of them.'

Use of 'any of you'

This phrase is used when addressing more than $2$ people.

Using quantity words alone

Words like 'some', 'most', and 'half' can be used alone without a noun when the meaning is clear (e.g., 'Some cars have four doors and some have two').
