洋風
ようふう · youfuu · JLPT N1 · noun
manner
洋 = ocean/overseas (Western) + 風 = style, so 洋風 = Western style
洋 originally meant the ocean; in Meiji-era Japan it came to mean things from across the sea, especially the West. 風 means style or manner, so 洋風 literally means overseas-style.
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.
