Language use can affect the listeners’ mental imageries, feelings, emotions, and other perceptions. Therefore, marketing ads intentionally use language-shifting and it is strategized to elicit the desired impact on customers. Despite its influential impacts, previous studies rarely observe the elements of ads being language-shifted and its functions. This study aims to investigate the language shifts within ads and the functions for shifting the language in advertisement texts. The research questions of this study are “What information in the advertisements are being language-shifted?” and “What are the functions of the language shifts in the ads?” This study uses syntactic analysis to reveal the language shifts and the elements of sentences being shifted, along with the functions of those shifts. The implications of this study are as a reference for future advertising in strategizing the language use within ads and evaluating the function of the language shift to achieve the desired impact.
