Abstract: Researchers in the second and third waves of Tolkien studies in the UK and the USA in the 1970s throughout 1990s continued to dig as their predecessors did in the areas of the themes, archetypes, allegorical and symbolical meanings, Christian allusions, autobiographical features, political metaphors of Tolkien’s writings. They also explored new areas and achieved significantly on the topics of the languages Tolkien created and Tolkien’s philosophy of Language, the correlation between Tolkien’s religious belief and his writing, the question of time, Tolkien’s “mythology for England”, the cause for the difference between Tolkien and the modernists. By this time, Tolkien studies had gradually acquired an established position as a serious literary research.
