Nymir is a modern American coinage with no fixed meaning, most likely built on Amir and Namir, which mean "prince" and "leopard" in Arabic, with the fashionable Ny- opening of Nyjah and Nylah. It belongs to a wave of newly formed -mir names that took off in the late 2010s. Nymir climbed from number 9333 in 2015 to number 2204 in 2025, its highest rank so far, with 65 boys given the name.
