• This error involves a very common confusion between two similar-sounding words: Affect vs. Effect.
Affect (Verb): To influence or produce a change in something. Since the news changed her emotional state, the verb form "affected" is required.
Effect (Noun): The result or outcome of a cause. (e.g., "The medicine had a good effect").
The Preposition: In English, we use the preposition "by" after "affected" to indicate the cause (the news). "Affected from" or "affected of" are grammatically incorrect constructions.
Quick Tip: Remember RAVEN — Really Affect is a Verb, Effect is a Noun.
