Thai Formal & Everyday

Twelfth graders learn that Thai has clear registers. Formal Thai (ภาษาทางการ) uses careful words and polite particles for news, documents, and official settings — even a special verb, rap prathan, for “to eat.” Everyday Thai relaxes the grammar and uses casual words like kin (“eat”) with friends and family. They sort settings by register.
