Questions & Answers about Dieses Buch ist interessant, aber das andere ist langweilig.

Why is dieses used instead of other forms like diese or diesem before Buch?

Because Buch is a neuter noun (das Buch) and it’s the subject (nominative case) of the sentence. The demonstrative pronoun dies‑ must be declined for gender, number, and case. In nominative singular neuter, the strong declension of dies‑ is dieses, so we say dieses Buch.

What case is dieses Buch in, and how do you know?

It’s in the nominative case, which marks the subject of a clause. Here, dieses Buch is what “is interesting,” so it must be nominative.

Why does andere have an -e ending in das andere?

In das andere, das is acting as a definite pronoun (“the other one”), and andere follows it. That combination triggers the weak adjective declension, where nominative singular neuter endings are -e. Hence das andere.

Is das in das andere an article or a pronoun?

Here it’s a pronoun, standing in for das andere Buch (“the other book”). The noun Buch is clear from context, so it’s dropped.
