7.04 Imperatives, exclamations and indirect questions

Use a period after a mild imperative or exclamation:

  • If you want to know who is going to change this country, go home and look in the mirror.
    —Maude Barlow
  • U-turn if you want to. The lady’s not for turning.
    —Margaret Thatcher

A sentence that is interrogative in form may be imperative in function and thus take a period (see 7.10 Requests, indirect questions and other uses):

  • Will you come this way, please.

Indirect questions are affirmative sentences and take a period, not a question mark (but see 7.10 Requests, indirect questions and other uses):

  • It is important for managers to ask why annual performance objectives have not been met.
