Etymology
The adjective "dural" is a modern scientific formation, directly built from classical Latin components. Its root, dur-, originates from the Proto-Indo-European stem deru-/dreu-, which carried the core meaning of "hard, firm, solid," a concept also evident in words like "durable" and "endure." In medical terminology, this root was combined with the adjectival suffix -alis (English -al) to specifically describe the "dura mater," a term literally meaning "hard mother" in Medieval Latin, referring to the tough, protective membrane. Thus, "dural" logically evolved from the ancient notion of physical hardness to precisely denote anything pertaining to this resilient anatomical layer.
