How to Say “Younger brother/sister” in Thai
น้อง
nɔ́ɔng
Younger brother/sister
ครับ (khráp) and คะ (khá) are polite particles — they depend on the speaker's gender. When calling out to someone, women say คะ (khá) (high tone), not the statement form ค่ะ (khâ).
When to use it
The mirror of พี่ (phîi) — น้อง (nɔ́ɔng) means "younger sibling" and is used for anyone younger, again far beyond literal siblings. This พี่/น้อง (phîi/nɔ́ɔng) age-based system is core to how Thai social address works, more so than fixed titles like "Mr./Ms." Using these terms conveys a warm, close vibe. That said, น้อง (nɔ́ɔng) is used somewhat less than พี่ (phîi) — with younger people you already know, you'd typically just call them by their nickname rather than น้อง (nɔ́ɔng) + name. น้อง (nɔ́ɔng) + name is mainly reserved for addressing little kids, babies, or pets.
Why you've seen it spelled differently
You may have seen น้อง written as: nong, norng, nawng.
There is no single standard for writing Thai in the Roman alphabet — phrasebooks, road signs, and tourist guides each follow a different system, and many just invent their own spellings. The romanization on this page uses a consistent IPA-based system that marks all five tones and distinguishes short from long vowels. The same word always gets the same spelling.
