Best practice
Always precede "compendium" with an article ("a", "an", or "the") or a possessive pronoun ("its", "this", "that") to ensure grammatical correctness.
Common error
Avoid using "compendium" without a preceding article. Saying just "compendium" or "it compendium" makes the sentence grammatically incorrect and unclear. Remember to use "a compendium", "the compendium", or "this compendium".
