Question

Which indefinite pronoun is always singular?

some
all
neither
several

Answer 1

The indefinite pronoun neither is always singular.

Neither is the negative counterpart of 'either' which is also singular. The basic principle of Subject-Verb Agreement says that the subject and verb must agree with each other, so you should use a singular verb because 'either' and 'neither' are considered singular; however, this principle is sometimes broken by a plural verb which can be used after 'either' and 'neither' informally.

Answer 2

Neither.

Step-by-step explanation:

Indefinite Pronouns, like collective pronouns, can be singular or plural. There are some rules to identify that. Like, "if it ends with -body, or -one, it is always singular".

Many can be both singular and plural. Several is plural. Some and All can be singular or plural.

Either, is always singular. So is Neither.
