Functions of Ideational Metaphor in English

Types of ideational metaphor in English considered in this research incorporate nominalization, verbalization, and adjectivization. Previous studies particularly highlighted functions of nominalization, leaving the other types of ideational metaphor unconsidered; in addition, expressions of ideational metaphor are not carefully selected while exploring the functions realized by these expressions. Against this backdrop, functions of ideational metaphor uncovered in previous studies are insufficient of coverage and typicality. Drawing on COCA in this research, a corpus of typical American English, expressions of the three types of ideational metaphor with significant attraction by means of the simple collexeme analysis are employed to analyze the functions that these metaphorical expressions actually realize in their linguistic contexts. The findings demonstrated that expressions of ideational metaphor could realize such interpersonal functions as authoritativeness and objectivity, such ideational functions as conciseness, abstractness, ambiguity, and semantic condensation, and such textual functions as formality and cohesion. Explanations to these realized functions of ideational metaphor are also provided. This research is of great significance in that the documented functions are typical and representative of ideational metaphor in English.
