Bryan Garner opens by distinguishing merely grammatically correct business writing from genuinely clear, effective business writing, arguing the latter requires deliberate craft beyond simply avoiding grammatical errors.

Why this distinction matters for business communication:

• Grammatically correct writing can still fail to communicate clearly and persuasively if it lacks the deliberate structural and stylistic craft genuinely effective writing requires
• Garner's guidance addresses this fuller scope of effective business writing, beyond just grammatical correctness, providing more comprehensive practical value
• This opening establishes the book's broader scope, addressing genuine writing craft rather than merely grammatical correction

This opening establishes the book's comprehensive scope, distinguishing genuinely effective business writing craft from merely grammatically correct but potentially unclear or unpersuasive writing.
