Etymology
The compound "soft-shell" is a transparent combination of two native English words. "Soft" originates from the Proto-Germanic samftijaz, meaning "level, even, smooth, gentle," a concept relating to absence of harshness. "Shell" derives from Proto-Germanic skaljō, meaning "a dividing piece," related to scales and things that split off. The compound logically describes the state of an arthropod's exoskeleton or a turtle's carapace during the molting or growth period when it has not yet hardened. This literal descriptor from natural observation is directly applied in zoology and gastronomy to classify certain edible crustaceans at a specific life stage.
Analysis
