either of them | us

1. “Neither” as a pronoun, is used to refer to not one or the other of two things or people mentioned. It indicates that both options are being negated or rejected. It is typically used in negative constructions or when presenting two options as equally unsatisfactory. For example:
   • “Neither of the candidates won the election.”
   • “I asked them both for help, but neither of them was available.”
2. “Either” as a pronoun refers to one or the other of two things or people mentioned. It presents a choice between two options. It can also be used in positive constructions when offering two alternatives. For example:
   • “You can choose either of the two books to read.”
3. “None” is a pronoun that means not any or not one of a group of things or people mentioned. It indicates the absence or lack of something. It can be used in both positive and negative constructions. For example:
   • “None of the students submitted their assignments.”

In the English Grammar Profile, B2 point 82 in the category of PRONOUNS quantity is defined as:

a wide range of pronouns (‘neither’, ‘either’, ‘none’) with ‘of’ followed by an object pronoun.

For example:

Gerda, I don’t think it would benefit either of us to show these.

listen

So in a yin-yang way, 

silence needs loudness and loudness needs silence for either of them to have any effect.

However most of this structure overlaps with Negation point 19, so we will only investigate ‘either of them|us’ in this post.

B1 in red.

There are only 2 examples in PELIC:

Arabic, Male, level 5, grammar class  B2/C1

Eventually when the woman was feeling that her life couldn’t get worse, the car in front of her suddenly stopped so she went to the other lane and crashed into the man’s car but thanks god nothing happened to either of them, the cars took all of the damage.

Korean, Male, level 4, grammar class B2

Most of the students who are living in Bundang might spend time making an excursion to either of them.
