An ELT Glossary : Parallel syntax

  • Definition : The repetition of a sentence, clause or phrase structure within a piece of text,which helps to give cohesion to the text. It may be used for dramatic or rhetorical effect 

  • Example  : "A small step for man, a giant step for mankind." (Neil Armstrong, as he stepped onto the moon for the first time)

  • Political speeches will often use parallel syntax as a persuasive, rhetorical device (eg Barack Obama - Yes, we can; Martin Luther King I have a dream). It's often found in advertisements for the same reason.
