새로

First attested in the Hunminjeong'eum eonhae (訓民正音諺解本 / 훈민정음언해본), 1446, as Middle Korean 새〮로〮 (Yale: sáy-lwó), from 새〮 (Yale: sáy, “something new”) + 로〮 (Yale: -lwó, “to, as”, instrumental or directional particle).

The etymology is no longer as transparent in Modern Korean because 새 (sae, “new”) has lost its noun sense.
