How to Say Hello in Thai — And Everything That Goes With It

Hello in Thai seems simple but there's actually a whole world around it worth understanding.

The standard word is สวัสดี (sawasdee). Men add ครับ (khrap) at the end — สวัสดีครับ. Women add ค่ะ (kha) — สวัสดีค่ะ. These polite particles are not optional in formal or semi-formal settings.

Sawasdee is used for: Hello, Goodbye, and Good morning/afternoon/evening — all of them. Thai uses the same word regardless of time of day. That's refreshing simplicity.

The wai (ไหว้): Alongside sawasdee, Thai greetings typically include the wai — pressing your palms together near your chest or face and bowing slightly. As a foreigner, you're not always expected to wai but doing so correctly earns enormous respect. The higher the hands relative to the face, the more formal the greeting.

Casual alternatives: Friends often say ไงวะ (ngai wa) — extremely casual, roughly "hey." Never use this with older people or people you've just met.

Asking how are you: สบายดีไหม (sabai dee mai?) — Are you well? The standard response is สบายดี (sabai dee) — I'm well. This exchange is your first real Thai conversation and it never gets old.

A tip on tone: Sawasdee uses a mid tone on "sa," a rising tone on "was" and "dee." Thai people recognise the word even if your tones aren't perfect. But work on the tones — it matters more in other words.

Learning how to say hello in Thai is three minutes of effort that opens every door.
