Meaning
Expressing sympathy or condolences.
Cultural Background
Thais often use 'Sia-jai-duai' even for small things to show they are 'Nam-jai' (generous of heart). It's a way to build social harmony. At funerals, it's common to follow 'Sia-jai-duai' with a wish for the deceased to go to a good place (Su-khati). In business, expressing sympathy for a client's personal loss is a key way to build 'Guan-xi' style relationships in Thailand. On social media, 'Sia-jai-duai-na' is often shortened to 'เสียใจด้วยนะ' or even just 'Sia-jai-duai' with a sad emoji.
The 'Na' Factor
Always include 'na' when talking to friends. Without it, you sound like a robot reading a script.
Avoid 'Sia-jai' for Apologies
If you break a friend's phone and say 'Sia-jai-duai-na,' they will be confused and possibly angry!
