吐火罗人是最早定居天山南北的古代民族之一,其传统疆域主要位于克拉玛干沙漠,疆界以北为天山,以南为昆仑山,以东是广阔无垠的戈壁,以西则是威严壮阔的帕米尔高原。目前国内外学术界对吐火罗的研究诸多,尤其对吐火罗语的研究已取得很大的成就,但就其本身依然存在很多问题。本文在前人研究的基础上进一步对吐火罗语做以探究,并根据笔者的学术经验提出自己见解。 Tocharian is one of the earliest ancient peoples to settle in the north and south of Tianshan Mountains. Its traditional territory is mainly located in the Kalamakan Desert, north of Tianshan Mountains, Kunlun Mountains to the south, vast expanse of Gobi to the east and magnificent to the west Pamir Plateau. At present, there are many researches on Tochallan by domestic and foreign academic circles, especially great achievements have been made in the study of Tocharian, but many problems still exist in itself. Based on the previous studies, this paper further explores Tocharian language and puts forward my own opinions based on the author ’s academic experience.
