Morphology

seaweed = sea + weed (transparent) = sea + weed

The meaning is a straightforward combination of 'sea' + 'weed' meaning a plant from the sea and is directly inferable by learners who know both components.

Etymology

Seaweed comes from the simple parts sea and weed, where weed originally meant 'plant'. So Seaweed literally means 'sea plant', which explains why the word refers to the large plants or algae that grow in the sea.
