Explanation

เฮ้ย is a forceful interjection that comes out at the moment of a strong reaction. It may stand alone or be followed by expressions such as จริงเหรอ “really?”, ทำอะไรเนี่ย “what are you doing?”, or ระวัง “watch out.” Its uses—surprise, admiration, objection, calling someone, and stopping someone—share the core sense of an immediate, emotionally charged reaction. Among close friends it can sound lively and familiar, but an angry tone can make it confrontational.

Usage

Common in conversations among close friends, chats and social media, reactions to unexpected news, expressions of amazement, forceful calls to a friend, and sudden objections or warnings. It is also frequent in informal dialogue in movies and TV shows.

Caution

This is highly informal and can sound rude or confrontational when directed at someone. Avoid using it with superiors, strangers, customers, or in formal settings. To get someone’s attention politely, use ขอโทษครับ/ค่ะ, meaning “excuse me.”
