Tidbits about the Thai Language

 Thai is the official language of the constitutional monarchy of Thailand, a country with a population of 66 million people located in Southeast Asia.

 Thailand has been closely involved with Japan in modern history. Most Asian countries who were embroiled in the conflict of the Pacific War became colonies of Japan, European countries or the US but Thailand was able to avoid colonization. The Franco-Thai War started in 1940 in Thailand with Thailand regaining territories through signing a treaty in Tokyo with intervention from Japan in 1941.

 As the Pacific War broke out, Thailand and Japan formed an alliance and Thailand fought for the Axis Powers. Meanwhile, Thai nationals secretly agreed to help the Allied Powers focusing on England during WWII so they were able to avoid post WWII reparations and they were not linked to United Nations enemy state clauses. They did not become colonized, they maintained their constitutional monarchy and they were able to receive support from the US so they did not become Communist like some neighboring countries.

 Besides modifiers being placed after their object, the Thai language is very similar to Chinese. Adjectives, verbs and nouns modify other words to make idiomatic phrases so one word tends to be extremely long. Therefore it is difficult for even the translator to count the number of words equivalent to the number of English words so prices for Thai translations are set by number of characters.

 Thai characters are phonograms split into consonants and vowels. However, these do not directly express the tone of the character and there are complicated and irregular tones. Likewise, it is difficult to grasp the tone from only reading the Thai character. There are some basic rules, but these are not standardized in Thai language textbooks.

 In Thai script, the vowel is positioned above, below or to either side of the consonant and multiple vowel symbols may be written above. Vowel symbols may also be elongated vertically so there must be sufficient space above and below the character. Depending on the text, vowels are not necessarily elongated above or below the character or they can be only partially elongated so it is common to see excessively wide spaces between lines. In word processing software, the font must be designated to be displayed and problems such as the bottom part of Thai characters not being visible often occur. Due to these reasons, JOHO provides Thai translations in a PDF format.
