grammar and punctuation (Pearson product page)

  • Grammar items check whether sentences in a report are written correctly.

Grammar rules for clear reports (our study notes)

  • The verb agrees with its subject, not with a noun inside a phrase: "The box of tools was found" (box is the subject).
  • Each, everyone, neither and either take a singular verb: "Each of the witnesses was interviewed."
  • With "neither ... nor" or "either ... or", the verb agrees with the nearer subject.
  • Use the past tense consistently when describing events that already happened.
  • Pronouns must clearly refer to one person; repeat the name if "he" or "she" could mean two people.
  • Its = belonging to it; it's = it is. Their = belonging to them; there = a place; they're = they are.
  • An apostrophe shows possession: the driver's licence (one driver), the drivers' licences (several drivers).
  • Two complete sentences joined only by a comma form a comma splice; use a period, a semicolon or a joining word.
  • Use "who" for people and "that" or "which" for things.
  • A sentence fragment lacks a subject or a main verb and cannot stand alone.
  • Commonly confused: affect (verb, to influence) / effect (noun, a result); accept / except; then (time) / than (comparison); lose / loose.
