Parallelism or Parallel structure
Parallelism is the coordination of words, clauses and phrases in a sentence. Parallelism heightens the relation between connected elements by lining up noun with noun, phrase with phrase, and verb with verb.In Parallelism all linked words should match in form. e.g
1). Write injuries in dust, benefits in marble.
2). A living dog is better than a dead lion.
3). Any law that uplifts human personality is just. Any law that degrades human personality is unjust.
In the 3rd example, the construction of the second sentence is fully parallel with the construction of the second.The similarity in form helps to dramatize the difference between uplifts and degrades, and between just and unjust.
