The Vietnamese word "nghé" refers to a "buffalo calf," specifically the young offspring of a buffalo. In addition to its literal meaning, "nghé" can also describe a way of looking at something—specifically, to glance at it from the corners of one's eyes, or to sneak a peek.
In more advanced contexts, "nghé" can also imply a sense of suspicion or intrigue when someone is looking at something or someone without being obvious about it. For instance, in a conversation about relationships, you might say, "Anh ta luôn nhìn cô ấy bằng ánh mắt nghé, như thể đang tìm hiểu điều gì đó." (He always looks at her with a sidelong glance, as if he is trying to figure something out.)
While "nghé" primarily means "buffalo calf," it takes on additional meanings when used in different contexts related to the act of looking.
