Non-Sino-Vietnamese reading of Chinese 卯 (SV: Mão). Some dictionaries (such as Thiều Chửu's) consider it as Sino-Vietnamese, but the nặng tone in Mẹo is unlikely to be developed from the Middle Chinese rising tone and eo is unlikely to be a Sino-Vietnamese rhyme, compared to the likely tone and rhyme in Mão.
