Definition decision workflow

Check whether "thiopental" is acting as noun in your sentence. A definition is only useful when the grammar matches the way the word is being used.
2. Test the nearest option

3. Confirm with context
Use surrounding context as the evidence check, then read your sentence out loud to catch tone or rhythm problems.
