Rhetorical principles (unity, coherence, emphasis, variety)
Unity (consistency): Make sure that every sentence relates to the central
thought.
Coherence (logic): Make your statements flow smoothly, clearly, and
logically from sentence to sentence through
transitional terms or from a general idea to specific
points or examples.
Emphasis (power): Lay emphasis on points with the help of modifiers,
anastrophe (inversion), introductory “it”, repetition,
quotes, etc.
Variety (fun): Add variety by means of coordination / subordination,
active / passive voice, short / long sentences, simple /
complicated sentences, omission, synonyms(avoid
repetition), etc.
