What kind of sentence is this: "Whining is a big problem for Anthony's son."

Answer by  jeroboam (185)

It's a simple sentence that has a gerund as its subject. Whether George has difficulty in whining or whether George is capable of whining and the whining causes problems for him or other people is unclear, however, and the sentence is therefore ambiguous.

This is a short declarative sentence. It identifies the subject, whining, as an issue for Anthony's child. The verb in the sentence is 'is'. The nominative adjective is 'big problem'. The prepositional phrase is 'for Anthony's son.'
