    Distinguishes noun, verb, prepositional, and participial phrases from independent and dependent clauses. Equips students to recognize clause boundaries before studying sentence types.

  • Lesson 3 • Fragments and Run-On Sentences

    Identifies dependent-clause fragments, phrase fragments, and comma splices and provides correction strategies. Directly addresses the most common structural errors in adult writing.

  • Lesson 4 • Sentence Variety and Emphasis

    Applies inversion, fronting, and periodic vs. cumulative sentence patterns to create emphasis and rhythm. Bridges structural accuracy with stylistic effectiveness.

  • Lesson 5 • The Four Sentence Types

    Teaches simple, compound, complex, and compound-complex sentences with structural diagrams. Gives students a repertoire of sentence patterns for varied, professional writing.

Chapter 3See details

    Teaches present perfect, past perfect, and future perfect to express completion relative to another time point. Resolves the common adult confusion between simple past and present perfect.

  • Lesson 3 • Tense Consistency and Sequence

    Addresses tense shifts in paragraphs and the sequence of tenses in reported speech and complex sentences. Ensures coherent time expression across multi-sentence professional texts.

  • Lesson 4 • Progressive Aspect

    Explains present, past, and future progressive forms to express ongoing or temporary actions. Contrasts progressive with simple tenses to clarify when each is appropriate.

  • Lesson 5 • Simple Tenses in Context

    Covers simple present, past, and future with their time markers and typical uses in factual and narrative writing. Establishes the baseline tense system before aspect is introduced.

Chapter 4See details

Subject-Verb and Noun-Pronoun Agreement

  • Lesson 1 • Either/Or and Neither/Nor Constructions

    Applies the proximity rule to correlative conjunctions and explains exceptions with mixed-number subjects. Resolves a persistent source of agreement confusion in professional writing.

  • Lesson 2 • Tricky Agreement Situations

    Addresses indefinite pronouns, inverted sentences, and intervening phrases that obscure the true subject. Targets the agreement errors most frequently made by adult writers.

  • Lesson 3 • Core Subject-Verb Agreement Rules

Chapter 5See details

Punctuation for Professional Writing

  • Lesson 1 • Semicolons and Colons

    Distinguishes the semicolon's role in joining independent clauses from the colon's role in introducing lists and explanations. Builds on sentence-type knowledge from Chapter 2.

  • Lesson 2 • Commas: Rules and Common Errors

    Covers the eight primary comma rules including serial commas, introductory elements, and nonrestrictive clauses. Addresses comma splices revisited from a punctuation perspective.

  • Lesson 3 • Apostrophes and Quotation Marks

  • Lesson 5 • Punctuation in Digital Communication

    Adapts punctuation conventions to emails, reports, and online documents where style guides may differ. Prepares students to apply punctuation knowledge across modern professional formats.

Chapter 6See details

Modifiers, Parallelism, and Clarity

  • Lesson 2 • Misplaced and Dangling Modifiers

    Identifies modifiers placed too far from their referents and participial phrases with no logical subject. Directly targets a class of errors that confuse readers in professional documents.

  • Lesson 3 • Parallelism with Correlative Conjunctions

    Extends parallelism rules to both/and, either/or, neither/nor, and not only/but also constructions. Connects to agreement rules from Chapter 4 while adding a stylistic dimension.

  • Lesson 4 • Parallel Structure in Lists and Series

    Applies parallelism to coordinate elements in lists, series, and bullet points using matching grammatical forms. Builds on conjunction and sentence-type knowledge from earlier chapters.

  • Lesson 5 • Conciseness and Wordiness

    Identifies redundancy, nominalizations, and inflated phrases and replaces them with concise alternatives. Translates grammatical accuracy into the lean, direct style valued in professional contexts.

Chapter 7See details

Voice, Mood, and Conditionals

  • Lesson 1 • Indicative and Imperative Mood

    Covers the indicative mood for statements and questions and the imperative for instructions and requests. Establishes the mood baseline before the more complex subjunctive is introduced.

  • Lesson 2 • Second, Third, and Mixed Conditionals

    Covers unreal present, unreal past, and mixed-time conditionals with their modal and perfect verb forms. Completes the conditional system and connects to subjunctive mood from the previous section.

  • Lesson 3 • Subjunctive Mood

    Explains the present and past subjunctive in that-clauses, wishes, and hypothetical conditions. Addresses a mood that adult learners frequently avoid due to unfamiliarity.

    Integrates all chapter skills into editing and proofreading full professional documents such as reports and proposals. Serves as the capstone section, synthesizing the entire core curriculum.

  • Lesson 3 • Reported Speech and Indirect Questions

  • Lesson 4 • Gerunds, Infinitives, and Participles

    Explains when verbs take gerund or infinitive complements and how participial phrases function as modifiers. Resolves a persistent source of error in adult professional writing.

  • Lesson 5 • Nominalization and Formal Register
