Questions & Answers about Cierro la puerta cada día.
Why do we say "cierro" and not another form like "cierres" or "cierra"?
Why do we use the definite article "la" before "puerta"?
In Spanish, you typically use a definite article (la, el) before nouns in a lot of contexts where English might skip it (e.g., "I close the door" vs. "I close door"). Since you’re referring to a specific door, you use la.
Does "cada día" mean the same as "todos los días"?
Yes, cada día literally means each day, and todos los días means every day. Both expressions communicate that the action happens daily. There’s no major difference in meaning; you can use either one to say you do something every day.
