The word "yet" is often used to indicate that something has not happened up to the present moment but is expected to occur. For example, if someone says, "I haven't finished my homework yet," it implies that they plan to complete it in the future. This usage highlights an ongoing situation or an expectation. In contrast, "still" refers to a situation that continues to be true or unchanged over time. For instance, saying "I still have my old bicycle" means that the speaker possesses the bicycle and has not lost or given it away. Both words convey a sense of continuity but in slightly different contexts.
