ocean
🌊💰 Water 氵 + sheep 羊 (sound) = vast ocean beyond the flock's pasture
The radical 氵 means water. The right side 羊 (sheep, yáng) gives the sound. Sheep graze on land — add water and you get the vast ocean beyond. Extended to mean foreign (from across the ocean) and silver coins that came via overseas trade.
洋 — water radical 氵 + sheep 羊
洋 combines the water radical 氵 (meaning) with 羊 'sheep' (phonetic, hinting at the sound yáng). Originally it referred to a vast body of water or ocean. Later it extended to mean 'foreign' or 'overseas,' since foreign things came across the ocean.
