Another example is right here in good ol' Oregon. The weather phenomena we have multiple names for is: rain. I have visited other cities where their "rain" list is like our "snow" list: short and simple; one even has simply: light rain, rain, heavy rain.
But we also have another weather condition which we divide into minute distinctions. When I saw droplets on my window that were a little bigger than a dense fog and recalled no rain in the forecast, I decided to take a look. I pulled up the prediction for today and clicked to see the details of their forecast. I looked at the "conditions" row and this is what I saw:
2 AM = Mostly Cloudy
5 AM = Overcast
8 AM = Overcast
11 AM = Partly Cloudy
2 PM = Mostly Cloudy
5 PM = Partly Cloudy
8 PM = Partly Cloudy
11 PM = Mostly Cloudy
When I looked at them, I thought about the difference between "mostly" or "partly" cloudy, and how "overcast," which means clouds in the sky blocking the sun, is different from mostly or partly cloudy. Is "overcast" a synonym for "we don't know how much but it will be cloudy?"
