Read the following excerpt: she had no dowry, no hopes, no means of becoming known . . which language convention does the author use for effect?

The correct answer is: Parallel Structure

Parallel Structure helps the writer list or compare ideas of equal importance by the repetition of a chosen grammatical form or structure to add clarity for the reader.

In this case the writer used the repetition of the word no to show how the subject had nothing to live for, and to express a feeling of loneliness and isolation for the reader.

She had no dowry, no hopes, no means of becoming known...
