Grammar
The Grammar chapter of the 11th edition of the AMA Manual of Style focuses on how to avoid common grammatical and writing errors. Topics include often-encountered dilemmas: who vs whom, that vs which, the number vs a number, a vs an. Guidance on frequent stumbling blocks such as double negatives, subject-verb agreement, false singulars and false plurals, collective nouns, compound subjects, misplaced modifiers, verbal phrase danglers, and parallel construction is illustrated with updated examples. The discussion of verbs considers voice, mood, and tense. Avoidance of idioms, colloquialisms, and slang, as well as euphemisms and clichés, is advised in material intended for an academic audience. A subsection on grammar considerations in social media has been added, as well as inclusion of they as a singular pronoun. A list of additional readings and general references concludes the chapter.
