'Everyday' in Medical Writing: Avoiding Ambiguity with Precise Frequency Terms
"Everyday" is an adjective meaning "routine, ordinary" (everyday clothes). As an adverb, the correct form is "every day" (two words) meaning "daily."
Problem in Medical Context
- Ambiguous: "The patient takes aspirin everyday." (Adjective? Adverb?)
- Imprecise: Does not specify dose, timing, adherence, or duration.
