“Interjections are short exclamations like Oh!, Um or Ah! They have no real grammatical value but we use them quite often, usually more in speaking than in writing” (Interjections, 2001, para. 1).
While interjections are very short, they communicate a great deal because they are typically used to express emotion. “While any word that shows strong feelings can be an interjection, look for the usual suspects: Wow!, Zap!, Pop!, and the rest of the family” (Rozakis, 1997, p. 59).
Woops! Did I forget to include you in the zombie plan?
Because interjections communicate strong emotions, they should not be over-used. “With interjections, a little goes a long way. Use these marks of punctuation as you would hot pepper or hysterics, because they are strong and edgy” (Rozakis, 1997, p. 59).
