Parallelism (rhetoric)

Parallelism means to give two or more parts of the sentences a similar form so as to give the whole a definite pattern.Parallelisms of various sorts are the chief rhetorical device of Biblical poetry in Hebrew. In fact, Robert Lowth coined the term "parallelismus membrorum (parallelism of members, i.e. poetic lines) in his 1787 book, Lectures on the Sacred Poetry of the Hebrews. Roman Jakobson pioneered the secular study of parallelism in poetic-linguistic traditions around the world, including his own Russian tradition (Jakobson 1987).
