Expert writing Tips

Best practice

Ensure subject-verb agreement by matching the plural possessive "their" with a plural subject (e.g. "The rules serve their purpose").

Common error

Avoid using the plural "their" if the subject is singular. For a single item, use "serve its purpose" instead. Writers often mistakenly use "their" as a gender-neutral singular pronoun in contexts where "its" is more appropriate for inanimate objects.

Linguistic Context

The phrase "serve their purpose" acts as a transitive verb phrase where the verb "serve" takes the direct object "purpose", modified by a possessive pronoun. As noted in Ludwig, it is used to denote that the subject possesses sufficient utility to meet an expected outcome.
