About
螺 combines the insect radical 虫 on the left with the phonetic component 能 on the right. This structure places the character within the semantic category of insects and creeping creatures, while 能 indicates its pronunciation. Historical dictionaries record two distinct meanings: a small biting gadfly or horsefly, and a type of turtle or soft-shelled aquatic reptile. This dual usage shows how the insect radical was broadly applied to various small creatures, with the phonetic element helping to specify the exact organism.
