Thais are very polite in their language. When I intro someone, I will intro as Nong X, Pii Z but nowsadays young Thais are different, they like short sentence just like SG when we speak English. So most youngsters will intro, this is X or Z but this also depends on how well brought up are they..... If u understand Thai enough and notice speaking with a well brought up family, their Thai are very polite and well manner comparing to others.
Thanks for the marketing...
Thai sentence ends with "Krup" or "Ka" in a polite way. They will also use "Krup" or "Ka" to acknowledge. To use "Krup pom", it is even more polite and especially when u acknowledge an elderly.
Example for the above.
Tirak, "Ruk mai"
U answer, "Ruk ti sot krup"
Grandfather, "kow jai mai"
U answer, "Krup pom"
To speak to elderly Thai, polite language is very important. Must always "krup krup krup" but when speak to your FL/WL tirak then all these are ignored.... you can always hear, "errr" to acknowledge instead of "ka". If this is used to acknowledge the elderly, this ger will be scolded, in chinese, we call "没家教“
"Kow jai pa lah"
Husband is "sa mi"
