1. Europe

• Go-on: う (u)
• Kan-on: おう (ō, Jōyō)
• Kun: はく (haku, 欧く)、うたう (utau, 欧う)^{←うたふ (utafu, 欧ふ, historical)}

From Middle Chinese 歐 (MC 'uw); from the first character of the transliteration 欧(ヨー)羅(ロッ)巴(パ) (Yōroppa, “Europe”) (modern Mandarin ōu, Cantonese au¹). Character originally meaning “to vomit” (Middle Chinese 'uwX, modern Mandarin ǒu, Cantonese au²).

The kan'on reading, so likely a later borrowing.
