The Tibetan alphabet is an abugida of Indic origin used to write the Tibetan language as well as the Dzongkha language, Denzongkha, Ladakhi language and sometimes the Balti language. The printed form of the alphabet is called uchen script (Tibetan: དབུ་ཅན་, Wylie: dbu-can; "with a head") while the hand-written cursive form used in everyday writing is called umê (Tibetan: དབུ་མེད་, Wylie: dbu-med; "headless"). The alphabet is very closely linked to a broad ethnic Tibetan identity. Besides Tibet, it has also been used for Tibetan languages in Bhutan, India, Nepal, and Pakistan. The Tibetan alphabet is ancestral to the Limbu alphabet, the Lepcha alphabet, and the multilingual 'Phags-pa script.

The Tibetan alphabet is romanized in a variety of ways. This article employs the Wylie transliteration system.

The creation of the Tibetan alphabet is attributed to Thonmi Sambhota of the mid-7th century. Tradition holds that Thonmi Sambhota, a minister of Songtsen Gampo (569-649), was sent to India to study the art of writing, and upon his return introduced the alphabet. The form of the letters is based on an Indic alphabet of that period.

David Michael Curtis (born 10 April 1965 in Salisbury) is a former Irish rugby union international. He also played some first-class cricket while at Oxford University.

Curtis, who was born in Rhodesia, now known as Zimbabwe, made his debut for Ireland against Wales in the 1991 Five Nations. He represented Ireland at the World Cup later that year, scoring a try in the pool stage against his country of birth and participating in their losing Quarter Final team. In all he was capped for Ireland on 13 occasions and scored his only other points courtesy of a drop goal in an international friendly against Namibia.

He qualified for Ireland through his father Brian who had also represented his country as a wing forward after the second World War.

His four first-class cricket matches were for Oxford University in 1990, playing against Leicestershire, Glamorgan, Nottinghamshire and Cambridge. A right-handed batsman, he made 89 runs at 22.25.
