The present research investigates the multimodal aspect of ta’ârof, a politeness ritual essential in many interpersonal interactions in Persian. We studied the opening sequences of interactions in an Iranian talk show to illustrate how gestures are used to express self-lowering and other-raising strategies between the host of the show and his guests. To analyze our corpus, we used NEUROGES® coding system to annotate gestures. Three categories of gestures (on body, on person, and egocentric deictic) were investigated and the results showed that they all have a pragmatic performative function and contribute to the meaning construction of ta’ârof in greeting sequences. In addition, age and gender have been identified as influential factors in the use of gesture to express politeness in Persian.
