choppy writing
Choppy writing is awkward prose that bumps along following the same pattern, usually subject-verb-object. You can avoid or revise choppy writing by varying your sentence patterns—combining short, related sentences, subordinating some sentences to others as dependent clauses, and eliminating unnecessary words to turn some clauses into phrases. (See also conciseness / wordiness, sentence types, and sentence variety.) Compare the following choppy paragraph and the revised version (as the author actually wrote it).
