“จงขอเถิด แล้วท่านจะได้รับ จงแสวงหาเถิด แล้วท่านจะพบ จงเคาะประตูเถิด แล้วเขาจะเปิดประตูรับท่าน เพราะคนที่ขอย่อมได้รับ คนที่แสวงหาย่อมพบ คนที่เคาะประตูย่อมมีผู้เปิดประตูให้”
Mt 7:7–8
To my surprise, I’ve found out that the Royal Institute of Thailand has actually issued rules for the transliteration of foreign words into Thai! From all I’ve read about them, I should actually be surprised I didn’t think of looking it up before.
From what I can gather, and just as I’d imagined, they’ve come up with systems that attempt to reflect as much of the phonology of the original languages and yet represent as much of the original orthographic features and idiosyncrasies by the Thai script.
The languages whose standards have been published seem to be:
- Arabic;
- Chinese;
- English;
- French;
- German;
- Hindi;
- Italian;
- Japanese;
- Korean;
- Malay;
- Russian;
- Spanish;
- Vietnamese.
That means that, contrarily to what the title of this post says, there doesn’t seem to be an official system for Portuguese.
For many features of Portuguese, I could actually come up with a reasonable basic system derived from common rules taken from the published standards that would also be valid for Portuguese – the representation of /ʒ/ by ฌ, for instance; for others, however, I wouldn’t be able to trace any parallels at all and would have to rely on examples found online and, well, my own whim – such as how to deal with unique sounds or raised (neutralised) unstressed vowels (to represent phonology or to reflect orthography?).
