Morphology

sea + horse

The meaning is directly derivable from 'sea' (marine) + 'horse' (horse-like), describing an animal that lives in the sea and resembles a horse; this compositional naming is straightforward for learners. Many languages form equivalent compounds for this animal, and even if written as one word ('seahorse') the semantic transparency remains clear to a B1 learner who knows both constituents.

Etymology

Sea horse comes from the fish's shape: its head looks like a tiny horse and it lives in the sea. Because it swims upright and uses its curled tail to hold seaweed, people called the animal a sea horse, so today the name means 'a small marine fish'.
