[Grammar] these types of things/these type of things/this types of things/such type of things/

[Aamir Tariq]

One should not give out his/her personal details to strangers on social websites.

1. These types of things should be avoided.
2. These type of things should be avoided.
3. This type of things should be avoided.
4. Such type of things should be avoided.
5. Such types of things should be avoided.
6. Such things should be avoided.

Now, there is a mix of these possible options in my mind, I would like to seek your expert opinion on which of those are grammatical as well as natural.

• this type of thing for one type
• these types of thing for more than one type
• these things for more than one thing

If you keep it logical, it's clearer and more effective.

• these types of thing for more than one type

Funny you say that, jutfrank, and yet you reject these types of things - I'd rather find these types of people more logical than these types of person. Besides, in my humble opinion, these types of thing is more formal.

I don't "reject" these types of things if there's more than one type of more than one thing. I didn't mention it because it's not as common.

Can you show how/why you think these types of people is more logical than these types of person? Or why you think the latter is more formal?

It's just me. Types of (plural) go much better with people (plural) than person. Formal? Maybe because phrases with a singular form, where you can choose either, seem to be formal, as in Is (formal)/Are either of you coming to the conference? Lots of textbooks I've been through often find and call it formal.

One should not give out his or her personal details to strangers on social websites.

1. These types of things should be avoided. Yes. All three a plural.
   
2. These type of things should be avoided. No.
3. This type of things should be avoided. No.
4. Such type of things should be avoided. No.
5. Such types of things should be avoided. Yes. Both are plural.
6. Such things should be avoided. Yes.
   
7. And: This type of thing should be avoided. Yes. All three are singular.

Now, there is a mix of these possible options in my mind, I would like to seek your expert opinion on which of those are grammatical as well as natural.

Such is grammatical but not as natural as this, these, and those.

Pay attention to singulars and plurals! You wouldn't say "these boy" or "this girls"!

"In formal English, once the indefinite pronoun one is used, the same pronoun (or its supplementary forms one's,oneself) must continue to be used consistently – it is not considered correct to replace it with another pronoun such as he or she."

Yes. These are grammatical:

One should not give out information.
One should not give out his or her information.
One should not give out one's information
People should not give out their information.
You should not give out your information.

These are not:

One should not give out their information.
One should not give out his/her information.

 

[Raymott]

That is not acceptable in BrE.

It could be if the meaning is someone else's information, but not in the OP's context.

Yeah, I took it to mean his own information or her own information.
