The Himalayas theory proposes that Natural languages are languages that have developed naturally among humans, evolving over time as people communicate with each other. natural languages also evolved based on geographical features, including mountains, rivers, oceans, and climate. The Himalayan Mountains, serving as a significant barrier, influenced human migration and language evolution in ancient times. Over time, various factors, such as tribes, cultures, and civilizations, also played a role in shaping language development. According to the Himalayas theory, different civilizations adopted unique forms of language communication, spreading their influence to reachable areas. Isolated civilizations maintained distinct languages and cultures. Human languages changed with civilizations, evident in scripts like Egyptian hieroglyphs, Sumerian cuneiform, Mayan script, and Chinese characters. Chinese, due to the Himalayas’ barrier, retained original ideographic characteristics. This linguistic influence led to the categorization of languages into phonographic and ideographic groups, separated by the Himalayas. West Himalayan languages are mostly phonographic, while some East Himalayan languages, influenced by Chinese, are ideographic. Northern and southern Himalayan regions show a mixed east/west Himalayas languages. Research using the “International Alphabet Text” database identified distinctions in phonographic and ideographic languages. This study aims to address the lack of research on these linguistic features especially ideographic languages. Further research is needed to validate the Himalayas Theory comprehensively.
