一下
yī xià
In real, traceable use. Part of the curated seed collection; community review is coming.
A moment, a little: after a verb it makes the action brief and a request softer. 等一下 'wait a moment', 坐一下 'sit down for a bit', 介绍一下 'let me introduce'. In speech 一 is said yí here, before a fourth tone: yíxià.
Một chút, một lát: đứng sau động từ để chỉ việc làm nhanh, ngắn và làm lời nhờ nhẹ nhàng hơn. Giống “một chút”, “một lát” trong tiếng Việt: 等一下 (đợi một lát), 坐一下 (ngồi một chút), 介绍一下 (xin giới thiệu). Khi nói, 一 ở đây đọc là yí vì đứng trước thanh 4: yíxià.
