Singular or plural verb with 'or', 'either/or' and 'neither/nor'

Many of us get confused when we have to connect two subjects in a sentence by ‘or’, ‘either/or’ or ‘neither/nor’. Instinctively, we want to use the Plural form of a verb, but this is a mistake. Don't trust your instincts or native language behaviour.

It is a very simple rule to remember:

use a single verb form after ‘or’, ‘either/or’ or ‘neither/nor’.

For example 👇

Chris or John is working today.

Either my brother or my sister is at home.

Neither apple nor orange is good. I would like a banana.
