the winter

[Lenka]

We use the fireplace a lot in the winter, so my room is always nice and warm.

Why is the definite article used in front of "winter"? Do you always use the definite article with the seasons? Or do you, in some cases, use the zero article?

[mykwyner]

You could write this sentence with or without the article. Seasons of the year are some of the few nouns that work like this.

I detect a very sight difference in meaning:

"in the winter" - when [this] winter comes: "In the winter, we'll have a fire again."

"in winter" - "In winter, we [habitually] have a fire"

ps - on reflection, I'm starting to think that 'the' goes in the second case too.
