Some or Some of? / Most or Most of? (Quantifiers – English Grammar)

Quantifiers Used with Sentence Subjects

Here is a picture of George Clooney, a famous American actor. Which sentence(s) below would correctly describe his hair?

Some of his hair is grey? Or some?

  1. Some hair is grey.
  2. Some of his hair is grey.

The correct answer is . Why? To explain, let’s look at each sentence individually.

“Some hair is grey.” 

The word some is called a quantifier because it tells you the quantity (how much) of something. Other quantifiers include all, most, many, few, little, and none.

When we talk about something in general, we use the structure quantifier + noun. For example:

  • Most people like strawberries.
  • Many cities do not have public transportation.
  • Some animals can be good pets.

As you can see, these sentences are general. They aren’t talking about a specific group of people, cities, or animals.

However, the above sentence about George Clooney isn’t general. We are talking specifically about the hair on George Clooney’s head.  When you talk about a specific group, you use of, like in the below sentence:

“Some of his hair is grey.”

Anytime you talk about a specific group, you need to use of after the quantifier. Also, after ‘of,’ there needs to be a determiner (the/his/her/my, etc). Let’s compare some examples that talk about general and specific groups.

  • General: Most people like strawberries.
  • SpecificMost of the people I know like strawberries.  (determiner = the (also called an article))
  • General: Many clothes are made in Asia.
  • Specific: Many of my clothes are blue. (determiner = my (also called a possessive adjective))
  • General: Some webpages are not suitable for children.
  • Specific: Some of this website’s pages are for students. (determiner = this)

Basic Rules

  • If you are speaking generally, then do not use “of” or a determiner (the/my/his/her, etc). Some people have grey hair.
  • If you are speaking about a specific group, then use ‘of’ and a determiner. Some of my teachers have grey hair.

      “Some of _the_ United States’ people are..” is okay and “Most of _the_ United Nations are” is also okay.

    1. mb Post author (Posted on 10-5-2017 at 13:32) Reply

      Hello. ‘More’ is a quantifier. It is used before a noun. ‘I don’t have more questions’. It is often used for comparisons. ‘He has more time than I do’. Etc.

    which one is correct?

    or

    1. mb Post author (Posted on 7-23-2018 at 14:28) Reply

      Both make sense. You would use #1 when the reader knows each of the control design parameters (i.e. they are specific parameters that have been introduced). You would use #2 if you are referring to control design parameters in general.

    Is it okay to say ” some of the input work is used”

    1. MB (Posted on 6-12-2019 at 13:58) Reply

      The construction ‘some of the [noun] is used’ makes sense. I’m not sure what ‘input work’ is, however.

    If I’m talking about a machine, which was disassembled and I start describing what was done to its parts/components (the components are never named, because they are many and it does not matter) should I say:

    1. and some of the components/parts were cleaned.
    2. and some components/parts were cleaned.

    To me, 1. sounds better. But I am not a native speaker and I might be making a mistake.

    1. mb Post author (Posted on 8-8-2019 at 17:45) Reply

      Either works, but I prefer #1 as well.
