Create a list of words you say.

A controlled vocabulary is an organized list of terms, phrases, and concepts intended to help someone navigate a specific context.

Documenting language standards can reduce linguistic insecurity.

A good controlled vocabulary considers:

  • Variant spellings (e.g., American or British)
  • Tone (e.g., Submit or Send)
  • Scientific and popular terms (e.g., cockroaches or Periplaneta Americana)
  • Insider and outsider terms (e.g., what we say at work; what we say in public)
