Prepositions with paranoid

Paranoid about, of, in, with or over?

Paranoid about is the most common pattern for fears and suspicions. Other prepositions are more limited or context-dependent.

Quick answer

Which preposition is used with paranoid?

Use paranoid about for worries or suspicions: paranoid about privacy. Paranoid of is less standard and often replaced by about. With can describe behaviour or symptoms, while over may appear with specific worries. In usually introduces a separate place or situation phrase, not a direct complement.
