Bangkok is the name of the capital city of Thailand. Thais call this city that ‘Krung Thep’ or in a bit longer name which is not the full name of Bangkok that ‘Krung Thep Maha Nakhon’.
From Wikipedia, the full name of Bangkok in Thai is
‘กรุงเทพมหานคร อมรรัตนโกสินทร์ มหินทรายุธยา มหาดิลกภพ นพรัตนราชธานีบูรีรมย์ อุดมราชนิเวศน์มหาสถาน อมรพิมานอวตารสถิต สักกะทัตติยวิษณุกรรมประสิทธิ์’
‘Krungthepmahanakhon Amonrattanakosin Mahintharayutthaya Mahadilokphop Noppharatratchathaniburirom Udomratchaniwetmahasathan Amonphimanawatansathit Sakkathattiyawitsanukamprasit’
And the meaning is
‘City of angels, great city of immortals, magnificent city of the nine gems, seat of the king, city of royal palaces, home of gods incarnate, erected by Visvakarman at Indra’s behest.’
The full name of Bangkok is the world’s longest city name. I am sure that many people who now live in Bangkok or even were born in Bangkok do not know the full name of Bangkok. And, since there are many Pali and Sanskrit words in the name, very less people know the meaning of this city name.
Frankly, I myself could remember the full name of Bangkok, but do not know some words’ meanings. And, I could remember the full name because of the popular song named ‘Krung Thep Maha Nakhon’ by Asanee–Wasan, a Thai rock band. In that song, the full name of Bangkok is used as lyric. You can listen some parts of the song here.
