Sometimes, listening to Thai people speak, it seems like the word jai (ใจ) is everywhere.
เข้าใจไหม (Khao jai mai, Do you understand?)
ใจเย็นๆ (Jai yen yen, Chill out.)
คนใจดี (Kon jai dee, Kind person)
But what does jai mean? Jai translates as “heart” and has all the similar connotations that heart has in English, such as “spirit” or “inner being.” So it makes sense that jai is used to construct phrases that have meanings related to one’s heart, mind and spirit. more “Thai is a Language of the Heart”
