How to Say “I'm allergic to peanuts” in Thai
แพ้ถั่ว
phǽæ thùa
I'm allergic to peanuts
ค่ะ (khâ) and ครับ (khráp) are polite particles — they depend on the speaker's gender, not the listener's.
Word by word
When to use it
Say this when a waiter asks whether you are allergic to anything, or tell them before you order. If you already know a dish is usually cooked with peanuts, you can instead say ไม่ใส่ถั่ว (mây sày thùa) — don't put in peanuts — to have them left out entirely. Both patterns are reusable: แพ้ (phǽæ) + [food], as in แพ้กุ้ง (phǽæ kûng) — allergic to shrimp; and ไม่ใส่ (mây sày) + [ingredient].
Why you've seen it spelled differently
You may have seen แพ้ถั่ว written as: pae tua, phae thua, pae too-a.
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.
