Questions & Answers about En invierno duermo mejor con un edredón grueso y una funda suave.

Why is it en invierno and not en el invierno?

In Spanish, seasons are often used without the article after en when you mean during that season in a general sense.

• en invierno = in winter
• en verano = in summer

You can sometimes hear en el invierno, but it usually sounds more specific or stylistically heavier, like referring to a particular winter period or giving extra emphasis. In a normal general statement, en invierno is the most natural choice.

Why is it duermo and not yo duermo?

Spanish often drops subject pronouns because the verb ending already shows who is doing the action.

• duermo = I sleep
• duermes = you sleep
• duerme = he/she sleeps

So yo is not necessary unless you want to add contrast, emphasis, or clarity.

For example:

• En invierno duermo mejor. = normal, natural
• Yo duermo mejor, pero mi hermano no. = yo is used for contrast

Why does dormir become duermo here?
