Languages:
Nepal's diverse linguistic heritage evolved from four major language groups: Indo-Aryan, Tibeto-Burman, Mongolian and various indigenous language isolates. The major languages of Nepal (percent spoken as mother tongue) are Nepali (48.61%), Maithili (12.30%), Bhojpuri (7.53%), Tharu (5.86%), Tamang (5.19%), Newari/Nepal Bhasa (3.63%), Magar (3.39%), Awadhi (2.47%), Rai (2.79%), Limbu (1.47%), and Bajjika (1.05%).
Derived from Sanskrit, Nepali has roots in Sanskrit and is written in Devanagari script. Nepali is the official national language and serves as lingua franca among Nepalis of different ethnolinguistic groups. Hindi and related regional dialects Awadhi, Bhojpuri and Maithili are spoken in the southern Terai Region. Hindi is also widely understood by the many Nepalis who have lived in India. Many Nepalis in government and business speak English as well. Dialects of Tibetan are spoken in and north of the higher Himalaya where standard literary Tibetan is widely understood by those with religious education. Local dialects in the Terai and hills are mostly unwritten with efforts underway to develop systems for writing many in Devanagari or the Roman alphabet.
Religion:
The overwhelming majority in Nepal follow Hinduism. Shiva is regarded as the guardian deity of the country. Nepal is home to the largest Shiva temple in the world, the famous Pashupatinath Temple, where Hindus from all over the world come for pilgrimage. According to mythology, Sita Devi of the epic Ramayana was born in the Mithila Kingdom of King Janaka Raja.
Near the Indian border, Lumbini, is a Buddhist pilgrimage site and UNESCO World Heritage Site site in the Kapilavastu district. It is held to be the birthplace in about 563 B.C. of Siddhartha Gautama, a Kshatriya caste prince of the Sakya clan, who, as the Buddha Gautama, gave birth to the Buddhist tradition. The holy site of Lumbini is bordered by a large monastic zone, in which only monasteries can be built. All three main branches of Buddhism exist in Nepal and the Newar people have their own branch of the faith. Buddhism is the dominant religion of the thinly populated northern areas, which are inhabited by Tibetan-related peoples, such as the Sherpa.
The Buddha, born as a Hindu, is also said to be a descendant of Vedic Sage Angirasa in many Buddhist texts. The Buddha's family surname is associated with Gautama Maharishi. Differences between Hindus and Buddhists have been minimal in Nepal due to the cultural and historical intermingling of Hindu and Buddhist beliefs. Morever traditionally Buddhism and Hinduism were never two distinct religions in western sense of world. In Nepal, the faiths share common temples and worship common deities. Among other natives of Nepal, those more influenced by Hinduism were the Magar, Sunwar, Limbu and Rai and the Gurkhas. Hindu influence is less prominent among the Gurung, Bhutia, and Thakali groups who employ Buddhist monks for their religious ceremonies. Most of the festivals in Nepal are Hindu. The Machendrajatra festival, dedicated to Hindu Shaiva Siddha, is celebrated by many Buddhists in Nepal as a main festival. As it is believed that Ne Muni established Nepal, some important priests in Nepal are called "Tirthaguru Nemuni".
