Time deixis refers to the linguistic expressions that indicate the timing of an event in relation to the speaker's moment of utterance. Common examples include words like "now," "then," "today," and "tomorrow." These terms help situate actions or events in a temporal context, making it clear when something occurs. In communication, time deixis is crucial for understanding the sequence and relevance of events. For instance, when someone says, "I will call you tomorrow," the word "tomorrow" provides a specific reference point that is relative to the current moment. This allows listeners to grasp the intended timing of the action being discussed.
