Norman (1985) proposed connection with Austroasiatic; Ferlus (2013) noted a "[g]ood correspondence" between Proto-Vietic *m-ŋəːʔ (whence Vietnamese ngựa) and Old Chinese reconstructions like *m-qʰˁaʔ (Baxter-Sagart) and *ᵀs.ŋaʔ (Ferlus). Also compare Proto-Hlai *hŋaːʔ (“horse”), Proto-Kra *ŋja C (“horse”).

Alternatively, Smith (2011) proposed 午 (OC *ŋaːʔ)'s cognacy with 啎 (OC *ŋaːs) "to meet head on" and 御 (OC *ŋas) "to meet in (battle)" and suggested that "the moon at its full phase opposes the sun directly in the sky, meaning *ŋaaʔ 午 is probably to be glossed, given *-ʔ , ‘facing stage’". Schuessler (2007) regarded 午 (OC ŋâh) "to go against" as a mere graphic variant of 啎 and thus deemed the sense "to go against" distinct from the "earthly branch" sense.
