Subject-verb

[MsNyree]

I have a question about Eating Disorders. I want to know if eating disorders is singular or plural? Is this a correct sentence: Eating Disorders is a major problem in America or eating Disorders are a major problem in America. Eating Disorders is the subject, but is a singular subject or a plural. I was taught if the noun uses an s it’s plural.

[Anglika]

Anorexia nervosa is an Eating Disorder; there are several kinds of Eating Disorders.

"Eating Disorders" is plural, so needs a plural verb

Eating Disorders are a major problem in America.
