What it is

This lesson is about the small words that hold a sentence together and the look-alike words that are easy to mix up:

  • Articles: a, an, the.
  • Prepositions: words that show time, place or direction (at, on, in, into, between, among).
  • Conjunctions: joining words (and, but, so, because, unless, neither ... nor).
  • Interjections: words that show sudden feeling (Ouch! Aha!).
  • Commonly confused words: words that sound alike or look alike but mean different things (its/it's, affect/effect), quantity words (fewer/less), and words that repeat a meaning (return back).

Why it matters on the exam

The exam tests these words in sentence completion, error identification and sentence correction items. The choices often look almost the same (a/an, in/on, its/it's), so you cannot rely on how a sentence "sounds". You need a reason for every choice.

At work, these words make letters and memos clear. "Arrive at 8:00" and "the forms were sent to the principal" mean exactly what you want them to mean.

Rule 1 of 13A or an: listen to the first sound
Use a before a word that begins with a consonant sound, and an before a word that begins with a vowel sound. The sound decides, not the letter.
