Phi and nong — the most important family pattern
Phi = older — used for older siblings and respectful address
Nong = younger — used for younger siblings
Phi is also used to address someone older than you — very polite
Nong is used to address someone younger — affectionate
Thais use these instead of first names — more natural than using names directly
🇹🇭   Phi = older · Nong = younger — use these and you sound natural immediately   🇹🇭
