The Vietnamese word "kêu nài" is a verb that means "to beseech" or "to entreat." It refers to the act of earnestly asking or pleading for something, often with a sense of urgency or desperation.
In more formal or literary contexts, "kêu nài" can be used to express deep emotional appeals or situations where someone is struggling and is making a heartfelt request. It can also imply a sense of desperation or urgency in the request.
While "kêu nài" primarily means to beseech, it can also imply a more general sense of asking for something persistently. However, it usually carries a heavier emotional weight compared to simply asking.
