Morphology

sea + lettuce

The noun combines 'sea' + 'lettuce' in a directly compositional way to denote a leafy marine plant; a B1 learner who knows both words can reasonably infer it is a lettuce-like edible seaweed. This follows regular noun-noun compounding and common cross-linguistic patterns for naming marine plants, so the meaning is transparent.

Etymology

Sea lettuce is named for the simple image of lettuce growing in the sea: this thin, green seaweed has wrinkled, leaf-like pieces that really look like salad lettuce. That's why the name means the 'edible green seaweed' people gather and eat.
