'seaweed-like' originates from the combination of 'seaweed' and the suffix '-like', where 'seaweed' refers to marine algae and '-like' means 'resembling or similar to'.

The term 'seaweed-like' evolved from the need to describe objects or textures that resemble seaweed in appearance or texture.

Initially, it meant 'resembling seaweed in appearance or texture', and this meaning has largely remained the same in modern usage.
