Bhutan’s official language is Dzongkha and it is also the most common language spoken all over the country. The language is derived from the Tibetan language. Dzongkha has same alphabets and similar way of speaking as the Tibetan language but it uses a different script. Though Bhutan is a small country, its villages and valleys have remain separated and isolated with each other for centuries because of the torrential rivers, deep gorges and difficulty in commuting between the places. Thus, most of the Bhutanese valleys have developed their own dialects and as many as 13 dialects are spoken all over Bhutan. Dzongkha is more popular in the west while Sharchopka is spoken in the east. Nepalese immigrants settled in down south, continue to speak Nepali language. Bhutan Broadcasting Service in Thimphu broadcast news in all these three languages on short wave and FM..
