In the preface to Style and readability in technical writing, the authors assert: “No other book takes this approach [to technical writing].” That approach, which has produced quantifiable success in writing intelligibly and effectively in other fields, is sentence-combining. To indicate the technical nature of sentence-combining, the authors refer to it as “tinkering,” a process of manipulating word clusters until the writer has put together unified sentences that are “economical, clear, and readable.”
