With Cognitive Linguistics as its theoretical foundation, the paper probes into the issue of FOR TO complement constructions used mainly as verbal complementation. Based on literature review of FOR TO complement constructions, the paper reinterprets FOR TO complement constructions from the dimensions of its syntactical features and cognitive semantics, its differences from Infinitive To constructions, and the contexts in which FOR TO constructions are used within the framework of Cognitive Linguistics. The paper concludes that the past literature has not yet conducted their studies in the respect of the mental experience and cognitive rules of speakers; therefore, more emphasis should be laid on the cognitive perspective of speakers while construing the unique syntactic and semantic features of FOR TO complement constructions. With the final aim of better serving foreign language teaching, the paper intends to serve in some way as the beginning of further exploration on the internal logical relationship between various kinds of linguistic expressions and their corresponding meaning construal.
