ABSTRACT
And known for its multiple functions and meanings is a high-frequency word form in both written and spoken English. By analyzing corpora data this study investigates its varying grammatical and pragmatic functions the frequency patterns of each function in both written and spoken registers and the interaction between its spoken forms and functions in spoken registers. Such analysis aims to complement current understanding of pedagogical grammar and EAP/ESP discourse. In addition knowing various functions of a high-frequency form may be cost-effective for language learners and help consolidate and expand their current knowledge of a particular word form. This study concludes that functions and the frequency of each function of and vary across registers and that different grammatical and pragmatic functions reveal different sound patterns in spoken registers. Identification of the different functions that the same word forms can perform the frequency patterns of different functions and the interaction between sound patterns and their correspondent functions not only contribute to the description of general grammar and different functions and meanings of a particular lexical item but also has implications for language learning and teaching.
