Question

• If two singular nouns refer to the same person or thing, the verb must be
singular. For example,
My friend and neighbour is here.
Can you explain please ​

Answer 1

Answer:

When the subject of a sentence is composed of two or more nouns or pronouns connected by and, use a plural verb. She and her friends are at the fair. When two singular nouns joined by 'and' refer to the same person or thing, the verb is singular. For example: The secretary and treasurer has been arrested. NOTES: article 'the' is used only once when the two nouns refer to the same person or thing.
