Thai
        language reflects the positive attitude of general Thais. A simple and
        tonal language, it can be learned easily. Knowledge of Thai language
        always helps because it greatly enhances the conversational ability of
        one when in Thailand. Not many people in Thailand speak English and your
        knowledge of Thai would come handy on several occasions. 
Versions of Thai
Several versions of Thai language are spoken in Thailand. The dialect
        spoken in Bangkok and nearby areas is called Central Thai. Three other
        main Tai languages spoken in Thailand are Southern Thai, Northern Thai,
        and Laotian. Local varieties of these languages are also in vague.
        Various Thai dialects differ from one another mainly by vocabulary. 
Central Thai Version
General people of Thailand use local language at home but in office
        they use Central Thai. This is the language of government and business.
        Central Thai is the language which is taught in schools. 
Emphasis on Politeness
Thai language is inherently polite reflecting mutual respect.
        Conversations in Thailand are always pleasant. People avoid
        controversial subjects and never speak sarcastically or abusively. The
        language is always spoken softly. 
Grammar
Simplicity is a characteristic of Thai grammar. Words are not modified
        or conjugated for tenses, plurals, genders, or subject-verb agreement.
        Concept of articles is absent in Thai language. Tenses, levels of
        politeness, verb-to-noun conversion, and other language tasks are done
        with the simple addition of various modifying words. 
Tonal Language
Thai is a tonal language and you have to pronounce every word with
        proper tone to be understood. One has to remember both the phonetic
        pronunciation and tone of every word. One would need time to learn the
        tones of Thai words. 
Appreciation for Thai Learners
Most Thais in tourist areas can speak basic English. However they
        admire and appreciate efforts of those tourists who have taken the
        trouble to learn even a few basic greetings. A tourist speaking only a
        bit of Thai language would always be welcome. 
History
Thai, language of around 80% of population in Thailand originated in
        the area which is now the border between Vietnam and China.
        Linguistically, the language links to languages spoken in eastern Burma
        (Myanmar), northern Vietnam, Yunnan, and Laos. Written Thai Language was
        introduced by Ramkamhaeng, the third Sukothai period king, in 1283. The
        writing pattern has undergone little change since its introduction, so
        inscriptions from the Sukothai era can be read by modern Thai readers.
      Thai writing is based on Pali, Sanskrit, and Indian concepts.
