Questions & Answers about Este libro sobre política no es aburrido; en realidad me gusta mucho y realmente me hace pensar.
Why does the sentence use este libro and not ese libro or aquel libro?
Spanish has three main demonstratives:
- este / esta / estos / estas → this / these (near the speaker)
- ese / esa / esos / esas → that / those (near the listener or a bit farther away)
- aquel / aquella / aquellos / aquellas → that / those over there (far from both)
Este libro suggests the book is close to the speaker (physically or in the current conversation: e.g. the book in my hands, on my desk, or the one we just mentioned).
You could say ese libro or aquel libro if you want to show more distance, but that would slightly change the nuance. The sentence is perfectly natural with este to mean this book.
Why is it sobre política and not de política?
Both sobre política and de política can mean about politics, and both are correct.
- sobre often emphasizes topic/subject:
- un libro sobre política = a book on politics
- una charla sobre música = a talk on music
- de is more general, used for many relationships (possession, origin, content, topic, etc.):
- un libro de política can also mean a politics book / a book about politics.
Here, sobre is very common and maybe a bit more precise for “on the subject of politics,” but de política would also be fine.
Why is política feminine here? What exactly does mean?
