Not all language researchers today are unfamiliar with such terms as “context” and “synonym”, but they may not quite understand the term “contextual synonym”. This is only because contextual synonyms are still beyond most linguists’ eyesight up to the present1. In spite of this, contextual synonyms are very often used in real texts. Discussions on contextual synonyms may reveal some features between words in a language and may help language learners to comprehend better in their reading and do better in their writing. This paper will focus on the discussion of semantic relationships between contextual synonyms. These relationships might help us understand which words in what circumstances can be used as contextual synonyms
