|simpl. and trad.|
Attested as early as Late Middle Chinese, with 每 functioning as a meaningless particle. At that time, 你每 was an equilibrating disyllabic version of the emerging 2nd. sg. and pl. pronoun 您. During Yuan Dynasty, the creolisation of Mongolian and Northern Chinese to form the Han'er language resulted in immoderate usage expansion of the plural suffix -每, by analogy with Mongolian noun plural suffixes -ууд, -чууд, -д, нар. After the overthrow of the Yuan Dynasty and the decreolisation of Han'er, 你每 gradually developed into the present-day 2nd. pl. pronoun 你们. The origin of the suffix -每 is unclear, perhaps also an Altaic influence. See 您.
