一時

Mandarin: yīshí
Middle Chinese: iət-ʒɪei
English: one occasion, same time

Notes

This term can have a couple distinct meanings ("one occasion" or "same time") depending on how 一 is read ("one" or "same"), while 時 is a term like English "time" for time or particular occasions in time. 時 typically functions as a postfix temporal preposition like English "when" or "during" but becomes as a noun when modified by an adjective like 一.

In Buddhist translation, this expression became the standard way of translating Skt. ekaṃ-samayam.
