This is a pretty big thing to toss off without even one example.
Human language has rather many concepts that are inherently fuzzy, for example, cold and hot.
If the temperature drops to 0 degrees Centigrade in June, it is very cold. If it raises to 0 in January it is comfortably warm.
We did a demonstration in the 8th grade. There were three cups of water, one ice cold, one so hot that it could be barely touched, and one in the middle. We put one hand in the cold one, one in the hot one, and then simultaneuosly moved them to the middle one. The water was at the same time cold and warm.
