thâorài + stating age
Explanation
The tens are built from 1–10: sǎamsìp = sǎam + sìp, sìisìp = sìi + sìp. But 20 is special — yîisìp uses "yîi", not "sɔ̌ɔŋ". When the units digit is 1 in a compound number, use "èt": sìp-èt (11), yîisìp-èt (21), rɔ́ɔi-èt (101). Big numbers: rɔ́ɔi (100), phan (1000). State age with NO verb "pen/khʉʉ": phǒm aayú yîisìp pii (I + age + number + years). Ask age with "thâorài" at the end: khun aayú thâorài.
