The word "acidulous" originates from the Latin word "acidulus", which means "somewhat sour" or "slightly acidic". This Latin term is derived from the noun "acidus", meaning "sour" or "acidic". The "-ous" suffix, which is commonly used to form adjectives in English, indicates "full of" or "having the qualities of". Therefore, "acidulous" describes something that has a mildly sour or acidic taste or quality.
