If your favorite season is winter, I bet you enjoy the frigid air. When the air is frigid, it smells clean and feels refreshing. I like it! Where I live, the autumn is always hot, so when the heat finally leaves, I welcome the frigidity of winter.
But maybe you hate being out in the frigid temperatures!
Although we usually talk about frigid air, frigid water, and frigid places, we can also say that people are frigid. That's a bad thing! It means they're cold-hearted. They're mean. They ignore you. They don't care about you. They act like you're not even there.
Lastly, have you noticed how the word "frigid" sounds a lot like "refrigerator" (and "fridge" for short)? Those words are related! They come from the same Latin word meaning "cold, or frost." Which makes sense, because your fridge can keep food nice and frigid.
