Time deixis refers to the linguistic expressions that indicate the timing of an event in relation to the moment of speaking. Common examples include words like "now," "then," "today," and "tomorrow." These terms help listeners understand when something is happening or will happen, anchoring the conversation in a specific temporal context. In communication, time deixis is crucial for clarity. For instance, when someone says, "I will call you tomorrow," the word "tomorrow" provides a clear reference point for when the action will take place. This helps avoid confusion and ensures that both the speaker and listener share the same understanding of time.
