This grammar handbook emphasizes formal written usage, offering clues to help with comprehension. The seven sections discuss: (1) "Nouns" (e.g., most nouns can follow "the," and possessives can show more than possession); (2) "Pronouns" (e.g., pronouns come in small groups, and some pronouns defy logic); (3) "Verbs" (e.g., some plural subjects take singular verbs); (4) "Modifiers" (e.g., some words cannot be compared, and watch the pronouns that follow comparisons); (5) "Sentences" (e.g., compound sentences show related and equally important thoughts, and sentence fragments do not fully answer questions); (6) "Conjunctions and Prepositions" (e.g., four tricky conjunction pairs, and when to end a sentence with a preposition); and (7) "Punctuation" (punctuating by ear, and other punctuation marks). Check-up quizzes follow each section, with answers given at the back of the book. (SM)
