Acquiring a rich and ample repertoire of words and using them well are crucial to quality writing.

This chapter covers the choice of words in writing and the concepts of style, voice, tone, ethos, and persona. The word-level suggestions include a coverage of abstract and concrete words; arcane and archaic words; Americanisms versus Britishisms; biased words; buzzwords; cliches and colloquialisms; confusable words; dictionaries; doublespeak and equivocation; foreign expressions; idioms and intensifiers; jargon and gobbledygook; malapropisms; nouning and verbing; redundancy and verbosity; spelling; the thesaurus syndrome; weasel words; and figures of speech such as allusions, analogies, similes, metaphors, puns, and oxymorons.
