Sentence Fluency is the rhythm and flow of the language, the sound
of word patterns, the way in which the writing plays to the ear --
not just to the eye. How does it sound when read aloud? That's the
test. Fluent writing has cadence, power, rhythm, and movement.
Sentences vary in length and style, and are so well crafted that
reading aloud is a pleasure. The main focus of sentence fluency
are:
Rhythmic
Easy to read aloud -- inviting
Varied sentence length -- some long, some short
Tendency toward shorter, crisper sentences in tech/business
writing
