Relating to or containing acacia, or resembling the acacia tree or its properties.
From acacia plus the adjective suffix -ine, creating a descriptive form that means 'of or pertaining to acacia.' This follows the standard pattern for turning plant names into adjectives in English botanical and chemical terminology.
The suffix -ine is incredibly productive in English—it appears in masculine (leonine, waspine), animal (feline, equine), and plant-related adjectives, all building on Latin patterns that Roman naturalists started using 2,000 years ago.
