Containing, resembling, or relating to borax or boron compounds; having the characteristics or properties of boron-based materials.
From 'borax' plus the adjective suffix '-ous,' which means 'having the quality of'; used primarily in older chemical or mineralogical texts to describe boron-related substances.
The suffix '-ous' appears across thousands of English adjectives describing material properties, but boracous specifically shows how chemists needed precise language to distinguish between different boron compounds before modern spectroscopy could definitively identify them.
