Deixis

In Marvel’s blockbuster Black Panther, King T’Chaka, the sole ruler of Wakanda comes to visit his sister in her laboratory and she shows him two newly designed suits of the Black Panther. When the king utters “this one”, we would be puzzled by which suit the king really favors because we have no idea where his finger is pointing at. However, if you have watched this movie, you would know that the king is pointing at a darker suit because it is not too showy. T’Chaka’s combination of pointing and uttering “this one” conveys a complete meaning to his sister that he wants to try on the black outfit. This specification of the referent often falls into the use of deixis.
