The Spanish adverb "allí" is used to indicate a location that is relatively far from the speaker and the listener. It is equivalent to the English word "there."
When using "allí," it is important to note that the distance referred to can vary depending on the context. It can refer to a place nearby or a place that requires some travel to reach, but it generally implies a greater distance compared to the adverbs "aquí" (here) and "ahí" (there).
For example, if someone asks you where your car is parked and you point to a spot a few meters away, you would use "aquí." However, if you point to a parking lot across the street, you would use "allí."
